Hey,
I understand the feeling only too well
But having been through it, and come out the other side, I can honestly repeat the cliche and say "it does get better!"
Like MDB said, suicide is a permanent soluion to a temporary problem.
You're just going through a hard time. You WILL come out the other side. You are young! So much life ahead of you. You just have to take a few steps to improve things, and we're here to listen and give you our excuse for advice
Till you see your doctor, use the board as an outlet. We're listening. Or PM someone, even me. Many of us are set up for IM chat too. PM me if you want my details.
I do see a time when suicide might be a solution. For me, that's when I'm old and probably suffering from some horrible life-ruining disease, the cure for which would just give me a few months of pain before dying. I would like to think I could end things myself quickly and painlessly without putting family members and myself through a horrible, drawn out decline.
But that's a very special circumstance, and not one you're ready for. Seriously, your problems can be resolved in a reasonably short time, you just need to redouble your efforts. Please don't give up just now, it would be so terribly sad and it would cause a lot of people a lot of distress, including many people here.
BTW it's not you who's worthless, but a "boyfriend" who can't see past your temporary problems to appreciate the great person you are. I'd forget that guy, he's either immature or a bit of knob. You deserve MUCH better.
