Acne what else can I do?!

I e struggled with acne forever. And I hate it. Is so embarrassing and brings my self confidence wayyyy down. I think it's even starting to bother my boyfriend with how bad it is which is more upsetting. But like NOTHING works. Ive found my skin is pretty sensitive. I've tried products which only irritate my skin more, soaps, home remidies nothing has help. It either makes it worse, maybe clear it up a little bit or doesn't do anything. I don't eat junk, I drink water all the time, I wash my face every day, I keep my makeup brushes clean, we wash our pillow cases and sheets often. This is getting so frustrating and embarrassing. I don't even like running to Walmart or whatever without makeup on cause it's so bad sometimes. I've been to the dermatologist before years ago and they gave me a wash that only irritated my skin, same with two different creams they had me try. I haven't been back since. And I just don't want to spend a ton of money going and paying for something expensive which I know might be the only way. But I have bills that need to come first. What's your advice/suggestions.
