I have said a prayer for you.
Steer clear of hurting yourself - this will not help matters.
My cousin just recently died in his sleep, he was 37 years old. It was natural opposed to suicide, but it is still tragic. My aunt (his mom) found him in the morning with no one else around. She tried CPR until EMS arrived and when she could finally realize what was going on she completely lost it. This was a terrible blow to the family to lose such a young person (only 11 years older than me!). I firmly beleive that all things happen for a reason. God has his plan all laid out before we are even born. He knew my cousin was going to die and he knew how we would respond. We, however, didn't know. We have to trust in God that he will lead us through bad times. If you have accepted Christ as your Savior and truly beleive that he died for us and God raised him from the grave than you will have life eternal with him and should trust that he has good plans for you.
In my case I was in complete shock, but I immediatly prayed for the situation. I prayed for his soul, my aunt, and the family. Though I don't understand why this would happen, I trust God's judgement. My cousin died to serve a purpose in God's grand scheme, even though I don't see it yet. Maybe I never will.
I beleive that hurting yourself will only make matters worse. Give your life to God and let the Holy Spirit guide your descisions. Pray before you make any serious descisions. Talk to someone you can trust to help you through this.
I'm not a very good speaker, and sometimes I'm not a good listener, but I hope this helps you a little. I will say another prayer for you as this updates.
Life is not a party, it's the preperation for the party.
