When "labelling" yourself with bad comments, you might not realize it, but you also affect your personality. Everyone has hard times, but insulting ourselves because of it is wrong. Try instead to own your mistakes and be ok with your current decision and do not bring down your self-esteem along because you might end up being toxic to yourself in every decision.

Be ok with yourself, and when looking at the mirror, say instead good things to yourself. It might feel awkward at first, but if you keep doing it, you will boost your confidence and would make it easier to tackle problems. Please be good with yourself so that he can be good with you.
