Thank you for the responses

. After having written that, I do feel that some of it was through a fish-lens because I had been feeling down lately. Maybe my focus is on the negative too much sometimes? I often go mindlessly headfirst into thinking about my problems without thinking twice about the consequences later, which is where a lot of my stress and emotional pain comes from. Hearing your responses helped.
I do feel like I have the power to make myself happier, though. I'm sure surrounding myself with positive influences is a start...
CANDC, thanks for telling me a bit about your feelings. Sometimes it helps just to let things out once and a while, especially if you keep things inside often. I think it's true that there are a lot of people who do have their own problems. I feel like they have better coping mechanisms than I do, however.
IrisBloom, I really understood this. I often forget that stressful thoughts are also like bad memories, and I need to learn to not think much of the former, in the same way I have learned to avoid the later. I think it's great that you've learned to avoid these negative thoughts when you know they'll bring you down.
