Struggling with Albuterol Abuse: Need Advice

//TW// Drug Abuse I've been abusing albuterol for the past two years now. I can't tell if it's a problem or not. I take it in classes (often double dosed) I'm able to get work done, I just shake a lot and it hurts to breath and my heart rate increases. But I can do medical homework with it. It helps calm me down, like it just kinda slows my thinking down. Whenever I can't find it or forget it I get anxious and distressed. I use it to get through my days. I'm too embarrassed to talk to anyone about this. My therapist and most of my friends don't know. I don't want them to see me differently.
