new here but willing to learn & grow :)

Hellooo peoples
well i just joined this site today, hoping to be able to learn how to be able to have a better
health system, and grow. Im really motivated to stay on track of my diet. Ive been on a diet an off
and on again and off again for about 7 years now, so i figured its time to get started and get the ball rolling lol
Time to get serious about my health, because i dont want to have diabetes ( which my family thinks i might have),
so they think i should try my best at being active and losing some weight, and getting concerned about how i treat my body.
im willing to be focus, and i feel that if i work hard at this, ill finally be happy with myself, cause its hard sometimes to look in the mirror, cause i feel ashamed of myself, and whatnot, so im also doing this for my confidence.
Trying hard not to deal on the negative and work on being positive, So any advice or tips would be greatly appreciated.
