I'm not sure what your situation is exactly, but I can tell you I have had similar feelings. Im not going to say I understand what your going through, because your circumstances are different then mine, but I do have similar frustrations and feelings as you. I feel for you, I really do. And I'm sorry you are going through this.
I too thought about ending it all. But about 2 weeks ago you know what happened? A small spider, maybe 2 millimeters wide, was crawling around inside the store where I work. Instead of smashing it, I used a piece of paper to carry it outside and free it. It's that moment where I realized, If I thought such small, insignificant life was precious and valuable and deserving of being saved, how could I take my own? I can't reconcile my thoughts with what I did to save that spider. There was something intrinsically wrong.
I was at the park today driving my RC car and a guy who is also in the hobby invited me back to his house. He looked to be my age, if not a little younger.
He had a wife and a small child. It was that moment that hit me so hard. What a blessing and beautiful gift it must be to start a family with someone. To share and pass on your genetics with someone to bring new life into the world. I never really thought about how beautiful and what an enormous gift such a prospect was until I saw it today, with my very eyes.
If there's just a 1% chance I can have that happiness some day, I'm going to hold on for it. It's worth it.
