I want to be more confident, have less spots, have a hot body and be able to be myself around anyone, but where do i start?

There's a puzzling: contradiction here. You say you want to "be myself around anyone" but you also want to change yourself in fundamental ways. I recommend seeing a therapist who can help you understand your lack of self-confidence and your belief that you have to "have a hot body" to feel confident. Being physically fit is important but having "a hot body" might not be the solution. Dr. Anne
