First of all hello everyone and I hope you are all ok. 

I apologise if this is a stupid question or thread but I need some informations in order to see where am I. 

This post will be long so here we go:

8 years ago, I tried to smoke a weed. After couple of minutes, weed kicked me so hard that I blacked out for couple of minutes and after I regained "consciousness" I was scared to death because I couldn't remember how I get home. Day by day after this experience, I had panic attacks every day, my anxiety was at full power and I was unable to do simple tasks because of fear which weed gave me. Couple of weeks later, I was at school and suddenly one thing came to my mind and that was "what if I'm stucked in coma and everything is not real around me because I can't remember what happened to me during blackout?" . This thought haunted and scared  me for couple of months and then it faded. 

Couple of years later, I avoided almost fatal car crash and my mind again played trick on me with thought "what if I died in car crash and this is afterlife?". This thought was only for short amount of time in my head because I read somewhere if I am really dead or in coma, I wouldn't be able to learn new things. 

3 years ago I had emotional breakdown when my ex ended our relationship because she met another guy and later on I found out that she cheated on me with this guy last 2 months before she dumped me.
After this event I ended in psyhiatric ward. I was diagnosed with F 41.2 - mixed anxiety and depressive disorder and I got proper treatment for my condition which put me back to feel alive. 

Fast forward to 1 year ago, I met a new girl and we started relationship. Everything was great until one day, out of nowhere my mind was hit again with bizzare thought "how can I have girlfriend because I find myself ugly, what if she is not real and she is my hallucination?" 

The idea that she is hallucination is coming because I watched too many movies with similar idea like : The Machinist, Fight Club,A Beautiful mind and etc. 

I know for sure she is not hallucination because others can see her, even my psychiatrist can see her because when I came to this idea which gives me a huge amount of anxiety, my psychiatrist told me to show picture of us together so I showed her.

At the end, my psychiatrist suggested me to take olanzapine, only 2.5 mg to clear my mind. I was really good for some time but 2 days ago I saw post on reddit where one guy claims that he can see people which appear real as normal persons, that he can see every detail on them but they are hallucinations and this sh** triggered me so hard and put me back 1000 steps. 

When I saw that post, my chest almost exploded because of anxiety and my heart started to pump like 140bpm. 

I contacted my psychiatrist and once again she told me that it is impossible to hallucinate entire person in every little detail and that I'm not suffering from delusions or hallucination. She told me that this fear is irrational and it is caused by anxiety which is causing derealization.
The idea of developing schizophrenia scares the sh** out of me. 
Also I never hallucinated anything, I never heard anything in my head,  I just had those bizzare thoughts which gave me chills. 

What do you guys think from first hand? Am I suffering from something more than just anxiety or everything seems fine? 

Thanks in advance and sorry for my english :)
