Thanks for all your advice thus far. They come to the gym with me sometimes when they feel up to it which I think is good. Getting out of the house and around people is important I think. When they confide in me about problems some times it helps and sometimes I seem to frustrate them and they withdraw. I try to offer solutions or things to improve their mood but often they comment that I don't understand what they are going through. They often say that they have little to nothing in common with most people. Events such as social gatherings seem to bore them as they seem isolated even when in conversation. They often pretend to be interested in social situations because they think that's what's expected of them. Activities that they once enjoyed don't seem to invoke any reaction which I find confusing as I always do my favourite hobbies to cheer my self up.

Thanks again for the advice and keep it coming.
