This is going to sound strange, but I inadvertently create more stress for myself. I don't know why but this is what happens:

I begin to start thinking about what I have to do tomorrow. I'm obsessed with schedules, calendars, list. So I go over it in my head, then on to the next day, and so on until I go over every single detail of what I'm going to do each day for like the next two weeks. The I think, wow. That's a lot of stuff, imagine every single thing I'll have to do for the next month, year, etc. I do this repetitively, and I tend to pace back and forth in my studio apartment, which tends to just work me up and make things worse. I panic and get overwhelmed, and it's literally over nothing... lol. It's been a lot better lately. I still do it, but it's not nearly as bad as it was. It was actually creating problems in my life, I wasn't sleeping much, my feet would actually hurt from pacing so much, my hands would be cramped from checking and rechecking lists, I'd have panic attacks, and I'd literally not get things that needed to be done because I was so worried about everything in the future.

Now, my stress comes mainly from symptoms and college. I also stress about my body. I'm a normal weight but have an eating disorder. Sometimes it starts acting up and I get really obsessive, it's better than it was, in some ways at least
