What to do?!

Hey I don't know where to start really but I feel like I just need to get it out.

I haven't exactly had the best summer. I went home from uni to find out that my mates from back home were being very off with me and I got the impression that they were jealous of the friends that I had made at uni. Also I had a load of uni work to do and was stressed with the retakes and coursework. My parents seperated for a short period of time and I also found out some personal stuff about my family that no one had told me. To top it off the guy I was seeing cheated on me with another girl. I mentioned all of that on here before and at the end of august I thought everything was fine. My parents have got back together and are living together again, I made amends with my mates and I sorted everything out with them. I also got over the guy thing and found out that I passed my uni retakes and was ready for my next year.

Two weeks ago I came back to uni thinking everything was ok, but since I have been back I have broken down into tears so many times. Every time when I go out drinking I nearly always break down crying. I never ever used to cry when drunk only since I've come back. My self confidence is very low and I have become extremely paranoid. It has gotten so bad that I thought one of my close mates said something nasty about me last night and I went off into the toilets and cried. She came and found me and I told her about it and now I feel extremely bad for thinking it.

I have cried so many times now that everyone is probably getting seriously annoyed with me, I know that some are but I can't help it. I don't know why I am so emotional, maybe it's a way to let everything that has happened out but I wish I wouldn't. I am so embarrassed and hate the person that I have become, I really want to change but I don't know how? Is there anything that I can do to change, does anyone have any advice?

Sorry for the long essay, I know it's doesn't make much sense or in any order but I can't find a way to convey how I am feeling.

Thanks
