Ever just feel sad for no reason?

I can't shake it.

I think I just had a bad few months since december, I haven't really had anything go right at all. I also feel isolated and sort of alone. I've been worried about losing my home recently as well. I have a job interview tomorrow at least but I'm worried I'll go there and be sad.
I'm not great at not showing my emotions.

I just want something to go right again, something nice to happen.
