Perspective is everything. You sound suicidal to me, but it doesn't have to be like that. Life is not 'I want this or I must die'. It can be just 'I want this'. There doesn't have to be a decided end. Just keep breathing, and let the end come when the Reaper sees fit (which hopefully won't be soon). A life without problems is a dream, but it wouldn't be worth sitting through.
If your pain is deep, I can't provide a cure, but my medicine is distraction. People may say 'Get out and meet people'. Really? When you're alone and you feel like dirt, you don't have the enthusiasm for it and you will just end up depressing people. Just take baby steps. Distract yourself now, retreat to those distractions everyday to give you comfort, and then reach out when you feel ready.
