Meditation. Download a free 20-minute guided meditation and do it every day. Maybe at some point read "The Miracle of Mindfulness" by Thich Nhat Hanh.

I can provide a good guided breathing meditation on request.

Meditation will help you be calm and focused. It will help you recognize and work through emotions with a minimum of harm to yourself or others.

I'm definitely not advocating self-immolation, but the same training that let monks sit calmly as they burned to death in the 60s (in an attempt to call attention to the horrifying war in Vietnam) will definitely help you deal with your breakup, illness, work troubles, or loss of a loved one.
