HELP!

I need some help.Lately,a lot of things have been going wrong.I' going through a very abd stage where everyone seems to be irritating me like hell.What do you do when everything doesn't seem to be working out?You work so hard at something and you think you nailed it but then you realise that you didn't.You don't know who to trust anymore.Your closest friends don't seem to care about you anymore.AHHHHHHHHH.Your world is turning upside down.That's exactly how I'm feeling now.I miss the old days.Anyway,i welcome any kind of help you can give me.But please,try not to irritate me.Signing out!
