You are a loser/liar/stupid/hopeless, etc.
Do not be surprised to hear a lot of unpleasant adjectives and nouns that come from toxic people. If you deal with someone jealous or indifferent, they will be likely to use insulting phrases to describe your personality. In their opinion you might be a loser or a liar. Maybe they will say that you are hopeless or stupid. Ignore such people and avoid all sorts of contact with them. Isolate yourself from bad company and stay on your own. Your self-esteem needs peace and quiet now. Solitude is all you need to recover and concentrate. If people cannot make you stronger, then do not listen to them. They are using abusive words and phrases simply because they feel powerless.
