It's not easy for sure. In my case I found a girlfriend and started living somewhere else. So another change in life helps a lot. Maybe you could search for something like that. Go live in another city albeit for a temporary period. A pet programming job might also help. You might be still behind the pc. But at least it is not wasted with just gaming, movies etc. You could also try to search for a coach/psychologist who can support you going to the change process. Go for it. You will be rewarded.
