First time here

I never thought that I had a problem until recently. I've been struggling with low self-esteem since last year. In my country we're just finished secondary school and exams are coming up. Between the stress over exams and thought about what I'm going to do with my life I've come to some unpleasant realisations. I've bothered by a increasing lying habit due to my insecurity in comparison to how easy it is for my friends to socialise and how much more approachable they are. If I'm honest I've never done anything really exciting compared to everyone else and I don't feel I have a lot in common with them anymore. I make up stories and things that I've done so people would think I'm more interesting. Its not something I'm proud of at all. I have a good bit of self-disgust with myself because with just makes the lying worse because these lies are now common knowledge with them. If I come clean I don't know how they'll react but that unkown stops me from confessing. I know that if I keep doing it I know It would blow up in my face but this stupid habit is hard,with a built up anxiety over my bullshit it piles on top of everything.. I just want to get this shit off my chest and I actually feel a bit better after venting this out. I think I'll keep this A/C open when I feel I can't appraoch anyone about these things. 

I'm open to keep in touch with anyone who's involved in something similar to me. I don't know if I'll be any help but sometimes it helps to have someone to vent to.
