I too am like this. Meds have helped with the agitation I get but not completely. I find I can get quite b*tchy towards people which makes my job hard to tolerate. I'm fine at the start of my shift but near the end, I'm ready to strangle someone. Anxiety meds have helped me relax too. Don't feel so bad about not having friends or visitors. I have "friends" that I haven't spoken to in years. You can't help how you feel. If you're really concerned and want a change then maybe therapy can help? Just a thought. However I even avoid therapists lol. People get on my nerves very quickly and I much rather have my smartphone or a good book!
