Thanks all, appreciate the responses.
I feel a lot better today, amazing what a lot of rest will do, also football training and being around some mates helped. Thanks for all the concern, I don't think it's at the doctors stage yet but it comes and goes.
I have started putting a plan together in terms of going home regularly and also the long term plan for the future. That has had an immediate affect of making me feel like there's light at the end of the tunnell.
Thanks again, and I'll try to make future posts of a lighter nature. Good to hear that others are in same boat (well not nice but sure you know what I mean) and my feelings are completely normal.
