People sometimes describe me as a "golden retriever." I.E., I present as quite upbeat. 50% of that is just nervous energy, but the rest might just lie in having a poor memory. I can experience something quite negative, even traumatic, and basically forget about it once it goes away.

Still, I used to experience periods of intense negative emotions which basically stopped when I started taking meds. I think, as time goes on, the nervous energy that made me seem like a "golden retriever" has probably decreased, but I'm still, underneath, a pretty happy guy.

I have found that partly, happiness is greatly helped along by just not remembering, or not thinking about, the things that make you miserable. On a Buddhist level, just living in the moment you are in, surrounded by the things and situations you are in, without dwelling on the past or worrying about the future, lets you be much less miserable than you could be. Often, the place you are in right now isn't that bad.
