Why do I always feel depressed or anxious after dating?

I’ve been dating someone really wonderful for the past few weeks. We have a great time and so much in common, its almost creepy. The chemistry is great. I don’t doubt that he feels the same.

I always feel so depressed after seeing him, and anxious. This isn’t a feeling I get only after seeing him, but a feeling I have always gotten after being out or seeing anyone.

I can’t stop stressing about things that may have gone wrong. Things for example, my lips were dry and maybe that will deter him. I know this sounds ridiculous. I get so much anxiety from these small things that it has gotten to the point where I dread dating anyone.

Why in the world do I feel depressed after having a good time with someone? I know I am beginning to like this person, and it actually makes me feel sick. I’ve been contemplating ways to avoid the situation. I can’t understand why I feel this way. I am so afraid of it going wrong that I’d almost rather avoid it completely.

How can I improve upon this? Why can’t I just sit back, relax, and enjoy it? Things have just been going so well for me lately, I’m wondering when it is all going to end. Why can’t I ignore that feeling? Am I alone in having these feelings? Does anyone else ever feel this way?
