If you are thinking about how lacking you seem to be, then maybe doing the opposite would be beneficial. For example try engaging in positive self talk and find what things you are good at, what makes you a good person, and go from there. I think that attempting to change your perspective on things and the way you think about your life might help you.

I apologize for sounding like I am talking at you. That is not my intention. I wish I could give you better advice, but it is what it is.

Let me know if you ever want to talk. Sending hugs your way.
