I need y'all's advice

Delete • I`m in a loving relationship. I am a post office clerk. Im 21 years old.
I have been gaining a loosing weight since I was 8 years old. I lost a whole bunch of weight when I was 12 but of course it all came back to me in my high school years. Now I can't seem to loose weight. I go to the doctor every 6 months to get checked for diabetes and high cholesterol. Right now my cholesterol is under control and I don't have diabetes. I was checked for a thyroid problem and I don't have one. I really don't eat that much. I work out at least 3 days a week sometimes more. I watch what I eat, but I just can't seem to loose it. No rude comments because Idc what you think of me I just need advice.
