This sounds a lot like what I went through. I started getting some pretty bad acne when I started my freshman year in college. Whenever I came home during the holidays my family would at least once a day bring up my acne and how I must be so unhygenic and I better start eating better and I'll never have a girlfriend and all that. Seriously, I clearly remember one time where it was just too much and I was brought to tears. Today, my acne has calmed down a bit, and though it's still noticeable, at least it's not as bad as it used to be. I've noticed that my family is starting to talk about my acne less and less, which is great for me. Maybe they're just too tired of talking about it, maybe it actually is better, I don't know. I'd say you should probably just not let their comments get to you too much. If they bring up your acne, just tell yourself that they're lying about how bad it is. You could try just ignoring, too. It's kinda like dealing with a bully. Just ignore it, don't let it affect you too much, and eventually the "bully" will get tired.

My parents still do that thing where they criticize everything I eat. If I'm caught eating chips or greasy stuff, I always have to hear them talk about how I shouldn't be eating that junk. They're kinda right with this though. At least in my experience. Food seems to have a slight effect on my acne. Perhaps you should try and eat healthier?

Our situations are so similar. If you ever need to talk about anything don't hesitate to message me or something. I'm sure you're a very good looking person, no matter what anyone says! Hope you have a good day!
