Advice on body

Ok so im not liking my body at all. Im 165 lbs and im uncomfortable wearing shorts and teeshirts so really all i wear is long sleves and sweatpants or leggings. I honestly hate my body and ive tried diets i guess im just lazy. Anyways, i just wanted to see if anyone had ideas or comments for modavaton and stuff that will be easy for me to lose weight. I also have bad asmtha so sprinting and hard core stuff is not my type of thing. Please dont hate. Im just seeking help.
