What role do we play as the lamp in the room?

I think I just spend way too much time thinking. About everything. Definitely overanalyzing. Over and over. I can't seem to stop. I also want everything to work out for the best, and hope it does all the time. I also only want the best for other people and have absolutely no idea why anyone would be mean to anyone else. I also tend to do things I don't want to do sometimes because I'm scared of hurting other people's feelings if I don't. It's hard to feel worthy of being with the people who I think are incredible. Sometimes I just can't equate myself with how amazing they are. Sometimes I just sit back and appreciate how amazing they are instead of thinking about anything else.
