I'm scared/anxious about a lot of things now, I didn't use to be like this. What could be causing this, and what can I do?

If you're asking this here, my guess is that this question is on your mind, but you're not ready to say to yourself, "Maybe I should see someone about this." So let me be the first: Maybe you should see someone about this. Psychotherapy (Especially cognitive behavioral therapy) or Psychopharmacology (You can visit a primary care doctor or a psychiatrist) are two ways to address anxiety that's getting in the way of your daily life. Whatever's more appealing to you. The important thing to keep in mind is that we have a number of very effective ways to address anxiety these days, it's just a matter of seeking them out.

I felt that way after I had a heart attack at 32... It went away after some time...

this usually happens to me when i'm facing a big change and i'm not entirely sure what's coming next -- is that happening to you??

also, after a big traumatic event, the stress can manifest itself as panic or anxiety.

I'm facing a big stomach issue, going in for tests tomorrow. Why I thought the two things were unrelated is beyond me. That's probably it, but if it continues kneck was right. I haven't been ready to admit that I should see someone.

I see an Oncologist for check-up yearly. Breast cancer 11 yrs ago.. The week before I feel as tho the top of my head is going to blow off and my stomach clenches so that it is hard to eat. Same for yearly mammogram. Therapy w. the right person is not only very helpful but interesting. Try some meditative breathing for panic ( breath goes in and out from diaphragm and tummy inflates and deflates like a little balloon).But getting into the dusty corners of your mind takes more time. Good luck.

I just moved to a new town for a couple of month to intern in a company, and I feel the same though not to the extend of a panic attack, rather I worry much more about simple things I wouldn't even care about normally.
So a big chance or unusual circumstances in your life can increase anxiety, or well, I can say that for me :)

As someone who experienced panic attacks semi regularly, so much so it interfered with my ability to work, go grocery shopping and lead a "normal" life. While anxiety can be normal and even at times a good thing, when it begins to dictate your daily behavior, it's time to seek out a therapist. While I have been prescribed antidepressants, the depression came about only after the anxiety. A therapist can help you to identify the root cause, whether physiological or psychological. Mine was rooted in childhood trauma and a car wreck, but after six months I've improved dramatically. Good luck to you! You can get better!

oh, i just wanted to add, that I don't advise too not take it serious (I just reread my entry, and it could be read that way). I second txcub in seeking advise if it is interfering with your daily life, just wanted to add my expiriences in "light panic moments" as one could say...

After you have the tests, see how you feel. People don't realize that anger is a major sign of depression. After the tests if you still feel anxious or short-tempered, don't be afraid to see a professional - and ask yourself if anyone in your family has this type of feeling. Many things REALLY are genetic. If eventually at some point you decide that a medicinal remedy may be appropriate, you may find that what is effective in treating other members of your family will be effective for you too. The day I found out that my mother and I both took the same medication in the same amount, we well as a sister, was a real eye opener. I hope the tests prove to be the culprit, that they turn out to be nothing...
