Hello, I am new here. I'm concerned about my mental state right now and I was hoping for any advice. The reason I titled this as "overly emotional" is because I can't seem to control my emotions. One minute I'm fine (not worrying about anything) and the next minute I'm crying and I'm just an aura of negativity.

To elaborate, I just moved a couple of states. I'm not sad because I didn't have any good friends in my old state and I wasn't ever emotionally attached to anything the nine years I lived there. Now I'm in this state and I seem to notice a few patterns. The first is when I make a mistake. The other day, one of my coworkers introduced me to his girlfriend. I started acting strange and I got very awkward (I have social anxiety). Immediately after they left I had a mental breakdown and I couldn't stop thinking about how awkward and horrible I was and I immediately resorted to cutting him off. I won't answer texts, I'm just kind of ignoring him. I do this whenever I make a mistake. I become very depressed and proceed to cut the person out of my life. I'm getting tired of feeling all this guilt and shame and embarrassment.
Another instance was a few weeks ago, I laughed during prayer at my youth group in front of everyone and I was absolutely mortified. Since then, I can't look my minister in the face and I've slowly stopped going.

I know this seems like a dramatic reaction to a small problem and it will hinder me moving forward in society because I can't keep running from my problems but I can't seem to stop. I have no friends and I don't want a boyfriend. It seems like this reaction is uncontrollable and I hate feeling this way. Does anyone have any advice?
