Stupid acne

I’ve been struggling with acne for about a year/ year and a half and recently it’s gotten REALLY bad I have never seen my skin like this and I feel so horrible. Every time I look at myself I just want to cry, even putting makeup on you can see all the tiny bumps. I hate it so much. I feel like it’s ruined me. I never want to go out anymore I don’t even feel comfortable around my own family! I have soooo many tiny little bumps all over my forehead that never go away, on my chin I have HUGE pimples under the skin that also never go away, right when one goes away another pops up! My cheeks aren’t so bad I just get a a couple tiny pimples that I don’t mind but I do have a lot of scarring. I feel like I’ve tried everything. I’ve heard a lot of good stuff about cetaphil so I’ve been using the face wash and moisturizer but I think it’s making my skin worse. I don’t know. I’ve been waiting to get into the dermatologist forever but of course the day of my appointment gets canceled. Just my luck🤦🏼‍♀️. Does anyone have any tips? I need as much as I can get, I’m going on vacation soon and I’d like to at least get the bumps on my forehead cleared before I leave😭
