Today is just plain awful. My sleep schedule is extremely messed up so I don’t wake up until 3 PM. I wake up and decide to have a bowl of Oreos with milk (don’t ask why) bad move considering I just consumed at least 40 grams of sugar by my estimation. I go to “pleasure myself” if you will and my heart starts beating a lot faster than normally when I do it. I start to freak out so I run upstairs, grab my spray bottle (anxiety safety behavior) and I start spraying myself in the face to try to calm down or something idk honestly. I go to take my heart rate and that was the worst thing I could have done as seeing that number rise just made everything worse. So I go and take my dog outside so she can go play and I can try to calm down. My anxiety continues to rise and so I turn the hose on and spray some water because the sound is usually calming...well this time it didn’t help. So I go back inside and at this point I’m starting to freak out a little so I take my anxiety meds (0.5 Mg of Clonazepam) I ask my mother to come to my room with me and talk to me so I can try to calm down. I sit down on the floor and I turn my gas heat stove on and just try to relax but thoughts are just flying around, none of them good. Then I hear an ambulance pass by and this really scares me (I had the worst anxiety attack of my life back in may and I had to call an ambulance so there’s some trauma there) so I plug my ears as tight as I can. I’m still just bidding my time waiting for the clonazepam to kick in. Then I start to get panicky and start to feel like I’m gonna get hysterical but right then I decided I needed to tell my mother the truth. A truth that no 17 year old wants to tell their mother. “My panic attack was brought on by masturbation” luckily she was very cool about it and seemed like she already knew I did it. Nevertheless it was so awkward and I wanted to cry. Thankfully the medicine kicked in and I felt better. Here I am 4 hours later and I’m getting anxious again. I don’t know what to do. I’m afraid of having another ambulance experience or having to go to the hospital or having some unknown thing wrong with me causing all this. I know earlier was caused by the sugar and the strenuous activity if you will. I just don’t know what to do anymore and I’m afraid. 
TDLR: Had a scary anxiety attack 4 hours ago, am still anxious and don’t know what to do.
