I have no idea which relegion you follow....but ending your life like this is going to give you more pain even after death....in Islam if a person commits suicide then after his death he will be asked to keep repeating the suicide attempt till eternity....nothing can be more painful than that.
This life is going to end anyway u just have to deal with your problems for few or more years but if eternity will suck than u will have no other way to go.....think about it
