How can I be happy again

Four months ago I tried to kill myself. I’d love to say I’m glad I survived and I’m feeling better, but I’m not.

I’m still having suicidual thoughts and feel desperately alone.

It doesn’t help that this is the longest time I’ve ever been single.

I want to get better, I want to go out into the world and find someone. But I barely have the energy to leave the house.

What do I do?
