too skinny ? feeling insecure 😣 please read

so lately i have been feeling very insecure about my weight/appearance, this is a pretty recent thing because honestly i’ve never felt insecure about my weight or my appearance,, i’ve always been very comfortable in my skin and confident, i have always thought that i looked fine... i am 5’0 and i have weighed about 105-110 pounds since i was like 15 , i am 17 now. so i started getting insecure because everyone around me is ALWAYS talking about how skinny i am and how i look like i’m losing weight but i don’t see it !! everyone is always trying to force me to eat more and it makes me so uncomfortable !! like earlier i was in the kitchen with my boyfriend and his grandparents and his grandpa had made some food but i wasent hungry so when he asked if i wanted some i said no, he then said “ why are you not eating maddy, you need to eat. you had more meat on your body when i met you , you look like you are losing weight” and then he proceeded to make me a plate even tho i really didn’t want it !! but everyone was in the kitchen at this point and i felt guilty for not taking the plate so i just took it and forced myself to eat it, because then i started over thinking like jeez maybe i do need to eat more, that’s what everyone is telling me 😭😭 i feel like that’s all people are looking at now !! how skinny i am... what should i do when someone makes a comment about my weight ?? i get these comments a lot and they are really starting to get to me 😣
