Can I ever find peace and happiness again?

I am feeling worse than Ihave ever felt in my entire life. I am actually contemplating doing horrible, stupid things. I know its bad because the things that usually bring me joy or contentment, I have no interest in. In fact, nothing is making things better. What am I going to do?? I need to feel loved right now and people ae being the complete opposite. What is so wrong with me that people don't care????
