I am 24 year old male. Out of excitement I tried a small (very small) edible portion of cannabis for the first time. I felt weird after few hours. My heart raced and I got scared and approached a physician. He said it is ok and gave tablet for headache. I couldn't able to sleep well at that night. I felt like my heart is going to explode and woke up multiple time to urinate just to flush it out of my body. The effects of cannabis is gone, but the pounding heart persisted for a week and I couldn't able to sleep well. Over the week the pounding heart got normal during day, but back when I lie down. I consulted a psychiatrist, he prescribed agomelatine. Now pounding heart problem got controlled even when I lie down. But I couldn't able to sleep well. I woke up 2-4 times almost everyday. I also developed anxiety because of this. I got racing thoughts in my mind, mostly negative. I feel scared of almost everything. I feel so scared at dorm. So, I came back to my home where I feel somehow safe. I took a leave of absence from my university for few weeks. Sometimes I am even scared of whether I could get good sleep or not. I am so obsessed with it right now. Sometimes I sleep for like 5-6 hrs. Yet I feel sleepless. I can't able to concentrate on anything because of this and I feel like a different person. In an article, I found that some compounds in cannabis can trigger preexisting mental conditions like anxiety disorder. I had anxiety disorder like condition before for which I took some treatment and got cured. I have not felt this anxious before. I am scared whether I am loosing control etc. What can I do further to get myself back. I need to stop racing thoughts and worries. I also want to get my sleep back before it affects my studies. Anyone who have experience in such cases please help me.
