You should build up your self-confidence. In fact, there is absolutely no need to care about what others think of you. Being fat also has advantages, at least you need more strength.

The chest is a place where fat is easy to accumulate. Being fat will really cause this problem, so exercise more, lose weight, do aerobic exercise, jog and go on a diet!

Moreover, I remind you to go to the hospital for a check-up, to test the liver and kidney function and abdominal B-ultrasound.

I hope my answer is helpful to you ~
