My SO suffers anxiety and depression, so I know what you're going through. If she was feeling like this, I'd want her to take whatever time she needs.

You're a young cub yet, loads of miles ahead of you. Focus on getting your headspace right and the dating will happen when you're ready for it.

Talking yourself out of liking someone sounds like an excellent problem to have. If I could do that, half the mistakes I made in my life might not have happened.

OP if you haven't been to see a doctor yet, I'd recommend it. Like I say, my SO suffers similarly to you and since she's had medication, her life is a whole lot easier.

Inbox me anytime you want to chat.
