Is it normal that i have severe panic attacks a month after edible?

I apologize if this is a long post but I am desperately looking for help/hearing from people who had an experience similar to mine :)

I've never used any other drugs in my life and I've never been a big fan of Marijuana and only tried smoking it 3 times and didn't enjoy it much.

Two months ago (Mid February), I went on a ski trip to Colorado with a couple of friends who decided to buy gummies (5mg THC each). I wasn't much interested but after hearing that it's so much different from smoking, I thought I would take half of the gummy just for the fun of it and feel it out (worst decision I made in my life). After about an hour of bar hopping, it kicked in and I couldn't stop myself from laughing at almost everything and anything. It hit me hard and I was enjoying it.

We got pretty tired and decided to go back to our airbnb, and in the cab I started to feel a little anxious but nothing too crazy. Fast forward 30 minutes, I am sitting on the couch and I started panicking and I could hear my heart racing and beating like it was on a loud speaker system. I asked my friend how long this is supposed to last and he said just a few hours and that I should just go sleep it off. I went to bed and woke up the next day feeling a little spaced out/hungover but i told myself it would fade away after a few days.

For about a month, I was feeling a little off a few mins during the day but totally ignored it and lived my life normally and happily; until about three weeks ago when i was driving to meet my friends and out of nowhere had the most severe panic attack! I lost totally control over my body! and after a few hours, got another one! I started getting these attacks everyday since for about a week and my friend gave me some Xanax to help me stay calm.

After horrible days of being physically and emotionally ill (constant depersonalization, jittering, fear, irrational racing thoughts), I decided to go see a psychiatrist who prescribed to me a SSRI (Lexapro 10mg) to stop the panic attacks from happening. This is helping stop the panic attacks and some of the racing thoughts but my mind doesn't feel back to normal. I don't feel like my old self. I feel like I am messed up my life entirely.

I don't drink coffee or alcohol and needless to say that I don't smoke or mess with weed. I also never had any mental issues before this!

Did anyone experience this? Does this go away? Any advice on what to do?

Any help is appreciated. Thank you!
