I got married.

Well, I didn't get married to deal with it, but I no longer have any time for my brain to reach melancholy.

My sole alone times exist when I'm going on a run or commuting to/from work. When I'm running, my blood is flowing and I'm generally energetic and calm. During commutes, I'm also generally calm and previewing/reviewing the work day.

Aside from that, I've always gotten a lot of use out of a good therapist.
