Hi livinglife, I'm glad you're feeling a bit better now but maybe some of that sadness was from your friends going again (after you'd met them) after having been without them (missing them?) and then seeing them again. Are you going to get to see them again soon? or are there other friends you can catch up with- maybe not the same but............?
Still we're here for you too and if you're feeling depressed for whatever reason or no reason you can think of then we're here to listen and try to support you.
Best wishes
Alison
