Every day I think about ending my life but I just don't have the guts to do it.
Really? What makes you want to end your life?
I'm so messed up over my last break up, I've been thinking about it constantly.
Going through a difficult breakup and thinking dark thoughts is something that many other people have experienced. However, you should realize that these thoughts are temporary and you should not act on them as committing suicide emotionally affects everyone around you. If you keep on having suicidal thoughts you should reach out to a mental health professional and receive help in order to overcome them.
Should I die alone?
No! You should try surrounding yourself by people who love you and realize that death isn't something that you should embrace, but rather love is.
