Is this considered abuse or torture to my body?

i've been having trouble sleeping and i previously drank really strong heavy tea but that jacked up my sleep and for 7 months i've been having trouble sleeping...i have been sober from drinking tea for 17days now but i still have trouble sleeping..WHAT AM I GOING DO TO?!! i only sleep like 1-2hrs in the morning and i lay awake all night and i might sleep 3-4hrs if im lucky. and this winter, ofr some reason every winter i always eat alot and gain alot of weight..i always eat too much and feel really full after i eat.
