I am right about myself?

You spend way too much time judging yourself against the deeds of others, and this is folly. You need to learn to live in your own head, and stop being so harsh on yourself. I mean, all the things you have said about yourself, everybody feels at one time or another, but the trick is to not let it rule your everyday thinking. Just be yourself, and be the most excellent you that you can be, because there is no one else like you on this planet, and there never will be another you, so you are special, you just have to start believing it. Be the "pebble in the pond", go out and spread good will, be happy, and what you put out, will also reflect back at you. What you manifest lays before you!!!! But remember to do these things without expecting praise or recompense, do it because it is the right thing to do.
