@saved123 Lose weight for your health. But realise that our human minds are fickle beasts. If your mind is primed to find fault and be negative, it will find something negative to focus on, even if you have done an amazing job losing weight and getting healthier. So the trick is to not believe everything the mind thinks for you and to realise that you can choose whether to focus on helpful things or sabotaging things. Obviously the former is the way to go - but your depression wants to assert itself... it is a weird dance.
I was clinically depressed and it was like constantly looking into a distorting mirror - everything that happened was interpreted by the mind in the most negative light.
Once you are out of that depressed state, you can see it for what it is (and sometimes, if you learn mindfulness techniques, you may be able to see through it even from within the state itself, which is powerful. Once you realise that you are not your thoughts, your potential for change will be so much greater.)
