Hey there Jon, Maybe you should start telling your Girlfriend that you just want to be friends for awhile beacause you feel upset and would like some time apart. Save your money and maybe treat yourself to a TAKEAWAY and I think you need some TLC you need to look at whats bothering you and fix it.Sometimes there isnt a way to "fix it" you need time for yourself and maybe have some wine with your girlfriend and have a good time and see if she takes advantage of you. Keep talking and talk things out. Don't let yourself get down .If you feel its too much -go to the doctor and ask for some medicaiton and tell the doctor everything(Its there job to look after you the doctor won't mind,take something)
