Gym has made wonders for me. Most of my friends are either on crossfit or running groups. I have joined a kickboxing gym. This helps you on multiple levels: - It provides you a routine - It makes you meet other people - It makes you exercise regularly

All of the above stave off the loneliness.

Also, get a hobby where you mind focus on one thing only. Play a instrument. Draw. Solve puzzles. Jimmy Carr had a similar issue and he started to play with legos.
