Even if they’re not difficult, they still feel like a burden, and I’m very worried that I won’t have time to do them or that I’ll forget about them. I either put them off but constantly think about them, or I try to get them done as quickly as possible and get very irritated when something prevents me from doing them. I can never relax if I have things to do, even if they’re not urgent; they’re still a pain in my ass. I don’t know why I feel this way, and I think this is the reason why I avoid difficulties and my life sucks so much.
Use a notebook to write down TODOs. This will get them out of your head. You’ll be at ease knowing they are easily retrievable whenever you have some time for them.
If they need to be done at a particular time, note them down in a calendar (and set up reminders).
