Hi fellow reddit users. I am new to this forum and I am in dire need for help identifying whether or not I'm being obsessive-compulsive about my crush.
Sorry for the grammar and syntax mistakes I am bound to make; I feel jittery and my mind is kind of not at its best atm, so please bear with me.
For the sake of privacy, I am going to refer to my crush as A.
I've known A for quite a while, but I've never spoken to him. We just see each other on public transport every morning on the way to school but we've never spoke. However, in March, he started coming to the help out at a soup kitchen I regularly volunteer at and initiated a conversation with me. 
Just last Thursday, when we were talking, I was suddenly struck with an almost unbearable feeling of incredible fondness towards A. Since then, I have been sleeping little to no hours at all, and my heartbeat is constantly beating at an increased rate. In fact, this new found feeling had given me two panic attacks since Sunday, and I can't stop myself from thinking about him. I know it is normal to have butterflies in your stomach and increased heart rate when you see your crush, but my body has been stuck this way since last week. The clenching feeling in my chest and churning in my stomach just won't go away. 
My mood also went from being relatively okay ( I say okay, but really just emotionally dead from anti-depressants) to skyrocketing all the way to the moon and back; I've been so excited that I cleaned my entire house and finished 3 essay assignments in one single night.
However, recently, I've been falling down from that 2-day high and I can feel my sanity slipping away as I started to become extremely depressed and lethargic.
My therapist had always suspected me of having OCD, but it was never confirmed. What do you guys think? Is this OCD? Or am I just being paranoid and a drama queen?
