Why do I always feel tired?

Do you exercise? Exercise is one of thee greatest way to release the feel good natural chemicals in the body.

Oh and this insomnia you speak of, I’m like 95% sure you’re using that term lightly. I’ve got a friend who’s got legit insomnia, and this dude is borderline psycho. Not being able to sleep until 3–4am is not insomnia. This dude currently this week from Tuesday until Friday has not slept

Now about my sleep. It’s not great.
If you’re lifting 6 times a week, then you better make sure that you’re eating and sleeping enough. Sleep is good. Maybe take an additional rest day and see how you feel.
As for sleeping tips, I basically turn every electronic device off and read for an hour before I hit the hay. I also sleep in a completely dark and cool environment.

I’d still see a doctor if I were you, because it could also be a thyroid problem.
Major props for exercising 6 times a week. I just did that last week and it is just brutal

This could be caused by many things: depression, sleep apnea and dehydration just to name a few. Drinking plenty of water may not actually be enough water especially if caffeine is involved. Anxiety will simply exhaust you and deny you recovery time. If you are experiencing anxiety that alone is enough to really mess up your sleep and energy. It could be other things like blood sugar or even thyroid. I’d be safe and have some blood work done. I would also start eating healthy and exercising regularly along with stress reduction if you are not already.

Here are the top choices not in any order:

1. Low iron
2. Whacked thyroid
3. Low vitamin D
4. Depressed
5. Not enough sleep in a 24 hour period.
6. Inconsistent caffeine intake.

The first 3 are blood tests and I think you should do them ASAP. Simple relatively inexpensive tests.

How old are you? Is your blood pressure nornal? Is your heart rate nornal?

Are you happy? You sound rather down. Why are you feeling anxious at night?

Sleep Apnea. Is sounds casual, but sometimes it kills people who ignore it. You are being oxygen deprived during sleep, which robs your organs of much needed repair. Get a sleep clinic appointment.

I was in the same boat and found out I had sleep apnea, which is a big deal if your a trucker,but since I was diagnosed I got a Cpap machine, my energy has come back I am not so dead tired anymore my wife and friends say it has made a 100% difference.
LOOK INTO IT.

If you are being honest about your diet an exercise, I have two thoughts:

One, you are a growing teenager. Metabolically, your body is on overdrive. It could account for why teens sleep so much when they can. Not to mention how go-go-go teens are. Downtime is important.

Thought two: it might be worth a quick trip to the doctor to rule out thyroid issues, or metabolic interference issues. Perfusion issues, etc. There are many ways the body produces energy levels. Most can be managed and manipulated.

Insomnia is tough. I have it, too. It doesn’t sound like apnea since you have troubles falling asleep. I have troubles staying asleep, and it sucks.

I will offer one bit of advice, as you are 15. Don’t turn to supplements like 5-hour energy or monster or Red Bull. You do not need that crap in your system. Period.

You should tell a doctor. It’s best to get checked out.

You need help with this problem, not just advice.
See if you can get someone to make you an appointment with a doctor, where you can have a chat with him and he can perform @JLeslie‘s 3 physical tests. If that doesn’t work, see if she will refer you to a sleep clinic.
At 15 I would not advise anti-depressants unless you feel like the problem is getting life threatening.
You’re eating very well, but are you eating enough, and late enough? Are you eating 3 decent meals a day? Please do. If you are eating 3 good meals, you might try eating 5 smaller meals so you’re eating closer to your bed time. Milk is good for you and is a major source of nutrients at your age. Maybe some turkey and a glass of milk near bed time.

I just noticed you did mention rapid heart rate in your original post. I hadn’t read it carefully. You really need your thyroid tested, you might be hyperthyroid.

Are you lonely at all? Loneliness is a big depressor for teenagers and sometimes anxiety can be part of depression. However, whackado thyroid can also make people sort of “artificially” depressed or anxious. I say artificial because once the thyroid is straightened out with medicine many symptoms begin to correct. Don’t take any meds to treat symptoms until you have had the tests to see if there is some sort of underlying cause. Unless you feel you might harm yourself, and I don’t get that impression from what you wrote.

Let us know what the doctor says. Don’t let him just dismiss you as being an average hormonal teen.

Just one thing to add to the excellent advice above: when you go to the doctor, get tested for Lyme disease.

You need to be checked out by a professional as many suggested.

If you are serious though about getting to sleep consider these approaches to bedtime.

Have a warm shower about an hour before bed, dim the lights and switch off the TV. Reading is a good way to pass the time until you sleep. Lights and action from TVs can make insomnia worse.

Have a piece of toast and a glass of milk if you can.

Write down the things that are worrying you before sleep.

Don’t pressure yourself to sleep, rather look for naps. Lots of naps do help.

Exercise each day even if only for 10 mins.

Put a little night light on? Or if light worries you make sure even the digital clock is covered.

Try white noise or soft meditations.
