Please HELP! Weight problems

I used to weight around 130 pounds, and I had the absolute worst constipation experience. Im talking about a week or two weeks worth of no bowel movement. Then I lost weight about 15 pounds. I had a regular bowel movement like everyday or every other day. But now I gained back some weight due to my family pressure, I now am having constipation. I didnt poop for almost two weeks and had to use laxative.

So....I also need an advice on this.

When I dropped 15 pounds, my family called me bad things like anorexic, stick, and so on. And they always pressured me to eat. I am not gonna lie. I always eat the same portion. I am not a big eater, but I like to have small meals thru out the day. However, my family is forcing me to have big meals many times a day, and I cant. I eat as they want me to, but I am not happy. I feel overwhelmed and not happy with the food I eat. I dont feel like the food is tasty anymore. So, as of now I gained 7 pounds back, and I am experiencing constipation, stomach ache, and unhappiness from being pressured to eat so much more that I can. Please help!
