Man Im sorry I cant be of more help to you other than to say this for now:
Not you nor anyone is boring. Your life may indeed be boring the shit out of you now, but that does not mean you are a boring individual. I'm in your position too, I feel like because my life is boring I'm boring but having read what you wrote tonight and meditating on it for a while I now think differently. What I write probably wont make a damn bit of difference to your situation, but I want tell you that by even making this thread you've at least helped one other person see their situation differently - that person being me. Thank you.
I know this is cliched to shit, but you have some beautiful positives going for you man; you have a crew you can hang with, a girl (man I'd so love a girl right now) and you're starting Uni in a couple of weeks.
Man I really wish I could be of more help. I feel the same as you a lot of the time - people avoid me because I'm lifeless because of depression and in those times I really dont have anything to offer anyone - and then other times my personality bursts out and people flock around me and I ask them why? Why do you want to be around a boring fuck like me? And they tell me because although there's a wave to my personality - a contrast between light and dark moments - I'm the most genuine person they know and everyone else is just predictably average.
Since you have a crew and a girl there is no chance you're a boring person man, these people see in you what you cannot see in yourself.
Listen, have you ever considered giving anti-depressants a shot? I have, about 8 of them and didnt work for me and I resorted to opiates and I can tell you that no amount of codeine will change things permanently - that can only ever be done while in a sober state. I might give them a shot again (the meds) - maybe you might consider it?
I wish you the best man, I'll keep an eye on your thread. Peace man.
