Hey there. I do understand your position. My personality will orbit more to depression as well, so it's a constant process and I am glad you are aware of that.
Something that helps me: reading and writing everyday. The reading helps me to keep my mind busy and primed on a subject of interest. The writing helps me to express and understand my own emotions. I find that talking and writing have a relieving effect because I externalize emotions in the process which allows me to understand myself better.
