Welcome to Healthcare Magic Forum
You can visit a counselor and talk about your problems, in person. Its not possible to discuss evrything on a forum like this.
Inability to express your emotions isnt an uncommon problem. Lot of ppl face this, but with time, little effort, some help form friends/family/conselor , one can overcome this.

Set small , simple goals, like losing 1 kg per month. I am sure this would be feasable.
