Thinking on locking in this semester

recently, I've been thinking that the reason that I don't seem to get over my negative thoughts, is, ironically, having too much free time. I thought this after finishing a semester with only 2 classes, I started feeling, not behind, but a little useless, all of my circle is usually busy in something, either a hobby, school or work, and I know I shouldn't compare myself, but that makes me realize that maybe it's that I have too much time just alone with myself, doing especially nothing, what discourages me to do or think of anything about the future; I'm not thinking on torturing myself with a lot of things, or try to work and study.

My plan is to get all of the things I've been "thikning on getting to it" for a long time (two years lol) before june 2025. That is, I'll enter a lot of courses, after getting a decent school schedule with more that 2 classes, obviously.
