having a panic attack 😭

ok I'm 22, and after a traumatic experience 7 years ago, I am terrified of throw up. even writting this makes me dizzy. I lost so much weight because I was afraid of food and had severe anxiety, borderline depression. I saw a doctor, she gave me medicine, didn't do anything. saw another doctor, put me on Zoloft and Zyprexa in 2015 and I slowly gained weight, started being more confident and not so afraid of food, my panic attackes decreased and in the last months I've had almost none. I'm taking less medicine, because in the beggining it made me sleepy and tired, and it affected with my school (I'm studying in Pharmacy). I'm still terrified of throwing up, I know it's an irrational fear but I can't help it. today I woke up at 6, went to school in the morning (had 1 cappucino), and then took my aunt to a shopping center (had another cappucino because I was feeling sleepy) and then had some KFC. I came back home, went to bed to rest and couldn't sleep, my heart rate was 90-95. anyways stayed in bed and 1 hour ago I started panicking again, maybe the food was too much or it was spoiled, or I had too much coffee, or that I am tired and can't sleep, or that I didn't sleep last night and I was panicking what if I'd had done some accident. and here I am, full on panic mode. my doctor has suggested I take 1 tab Clonazepam when I am anxious, but I haven't taken it yet. usually I find comfort talking to my mom, but we have a guest and can't bother her. so here I am, writing my heart out during a panic attack. trying to pull myself together. hoping it will be okay, and nothing is wrong and this is just my mind worrying about a stupid thing 😭 excuse my rant, I had to express myself
