I think I have a deep drug issue?

Ever since I was little I never had the attention, my siblings always did and I guess I look for attention from my school mates and friends by doing drugs. I dont do drugs because I like them or because im addicted I do it because it gives me attention. Even though it is the wrong type of attention I still crave it. I stopped doings drugs for a while(no problem) but I realized that I dont want the drugs I want the attention, I also cant stop the craving for attention. I have a horrible reputation as a drug user at school but to me attention is attention and i feel like if i cant get the attention from durgs ill find another way such as promisciouse and i am gay so it also helps me cope with some of the judgement, but u dont want to be another statistic of gay drugs user and addict. I really want help but i cant let my parents know. what do i do to get rid of the attentions cravings i have?
