Ask HN: How do you deal with depression?

The question is pretty straight-forward. I'm currently dealing with lots of pain and guilt from breaking up with a long-term girlfriend and leaving her with massive student loan debts. I'm having trouble focusing, losing weight, etc.

Aside from medication (I'm on some), how do you deal with pain/guilt/depression? This industry can be high-stress and we can all be hard on ourselves from time to time. Just interested in different coping strategies. Thanks.
