Hello, how is your day going? Hope you are better. I felt like this before, and I will tell you a secret, God will never give you a direct answer or a sign, but that is not a bad thing, he gives you the opportunity to take courage to get yourself out of the hole.
You must take the courage to talk to someone about how you feel, sometimes it seems that there is no one but I swear there is, you are not alone.
Find things that excite you, if these activities don't hurt you, then try these activities. Realize what you are worth and then find what you like to have a living for.
I know this seems silly, I also believed it before. Please seek help and take care of yourself.
