Is OTHER wrong in the post ? POST : *Mobile, sorry in advance

Background: I’m a 16 y/o male whose been chubby my entire life. My family never seemed to judge me about it, but they were all for me trying to lose weight. My entire family is overweight. I started my weight loss on December 2nd, with an initial BMI percentile of 94.
(0-5 Malnourished, 5-15 Underweight, 15-85 Healthy, 85-95 Overweight, 95-100 Obese)

Fast forward to now, and I have went from being in the 94th percentile to the 77th percentile. My family all seemed to be proud of me, but once I started losing weight, I realized I wanted to be more then “not fat”.
I’ve noticed that even though I have lost a good portion of weight, I still have a lot more fat then I thought I did to start (significant amounts on my love handles, which were what I was most insecure about when I started). I feel like they also just don’t really understand what my body is built to look like, because I’ve been chubby all my life, covering up my features, and how I always wear baggy clothes. 
My family doesn’t support me trying to lose anymore weight. Just to clarify, I’m not anorexic, or have any eating disorder. In fact, I pretty regularly eat like crap, with them next to me. I really don’t understand why, but whenever I bring up my goals, they all seem to say something along the lines of “Stop, you’re to skinny.” or “You need to plump up again.” I’ve explained multiple times to them exactly what I’m doing to lose weight, why I’m trying to lose weight, and why I feel that I haven’t met my goals yet, but they keep trying to shut me down, and don’t support me, which is something I really feel like they should be when I’m trying to make a pretty drastic change in my life.
The other day, one of my family members made one of these remarks again, and I had had enough. I told them all that they were being asshole for how little support they were giving me and them just wanting me to conform to what they want me to look like.
I’ve started feeling guilty about lashing out like I did, but I they know I don’t have an eating disorder, so I just don’t know why they keep shutting me down.
So, AITA?
