You just have to hold on and walk through it, I just lost a good friend to suicide and also recently went through a bad breakup. There's no good answer as to the way to get through it except that you just have to keep on keeping on. When I went through all of that I kept waiting for someone to say something that would make it easier, I found that unfortunately only time makes it easier to get through! It's like a big wound, it will get a little bit better everyday. I'm so sorry to hear that your going through all of that at once but just remember that your not the only one and that someday things will be better.
I cope when I pray a lot.
Prayer won't make everything change on the outside, but it does help me get through it. I wanted to kill myself. There were three times when I wanted to kill myself really bad. I'm Catholic, so I'm friends with Jesus mom Mary, and I feel she kept me from killing myself those three times. So I'll say a prayer for you. :)
Hey, didn't you ask the question about nice guys not being liked?
