I have actionable plans for the short-term future, which console me for what I would otherwise perceive as a directionless existence. In the mean-time, I'm working part-time and have to go to work each day, and I find that is quite exhausting sometimes but prevents me from feeling that my present tense existence is directionless as I am contracted for a few more months. So, that is an important routine to me. Also, I make sure to eat regularly, and go to bed at just about the same time each day, and this prevents food and/or sleep deprivation from interfering in the production of my mood state. Also, I continue to take medication despite doubts, which prevents medication withdrawal from interfering in the production of my mood state. Also, I am reading a book and that is what I do when I have energy, and I plan to read other books. Though progress is very slow, at least I know that I have a goal.
In all, it appears to me that both order and direction is important to the production of an inoffensive mood state, and in that sense both routines (sleeping, eating, part-time job) and goals (reading a book) appear quite important to me.
Also, I talk to people on the Internet, and therefore do not feel socially isolated.
