What is causing my ridiculous mood lately?

I’ve been way more impatient than I’ve ever been in my life. I’ve been getting extremely annoyed at stupid things (though I can’t help it) – things that would normally not annoy me. More than anything I’ve been getting annoyed with people who constantly talk about themselves and brag about whatever is going on in their lives. It’s not that I’m not happy for them because I truly am, but the fact that these people have been so conceited lately is just pissing me off.

Now my stress level has been higher than normal for a while now, same goes for my anxiety. I’ve been having smaller panic attacks – but more than I’ve ever had before. My pulse rate has been a bit faster, sometimes I have to try to calm my breathing.. even when I’m not doing anything overly strenuous. I do things to try to relax e.g. listening to relaxing music, closing my eyes for a few minutes, focus on my breathing and try to calm, etc.

I can’t exactly see a doctor/specialist right now because I have no insurance, so please don’t tell me to see a doctor. I know I have to and will once I have insurance again.

Anyway, any insight on why I might be feeling like this would be absolutely wonderful.

If you have any questions for me just let me know.
Sorry for the long description.
