Don't feel like you have to meet up. Do it only if you're up to it. Mild depression would be the time to re-socialise, I'd say. Any other time, when severely or moderately depressed, even if it's tempting or you feel obliged, I'd suggest you don't. First build confidence by being outside and being around people (without socialising).

I'm glad you decided to return to us . Here you can talk without anyone judging you, so please do.

Have you decided whether you'll continue medical school, when you're ready? I really would if I were you.

Just imagine: no one will be able to say something like "no one here is qualified to diagnose you". Sounds like heaven.
