Changed by aliens

I did not see an Ufo but I was changed 20,5 months ago by what I think can only be some external power. This is serious and not a joke.
 In September 2019 I was a primary school teacher, content in my work, with good friends and a supportive family.
Then from one second to the other I was not able to sleep anymore, I do not mean sleep less or poorly but no sleep at all. I was not tired or exhausted, I was rather exactly the same all the time. I formed sentences about how people sleep non stop and I did not know to whom. I was and still am also unable to imagine anything. For example if you ask me to close my eyes and picture a tomato I am not able to do so or if you ask me to think of a desert island - I can not.
 After 11 days I reported my self into a psychiatry and the gave me sleeping pills, but although I got all different kinds of pills I never fell asleep. After a few days the psychiatrists asked me how I felt about my snoring roommate, about my parents being on holiday... Then I realised that I could and still can not feel anything anymore. My senses are all intact although I do not have a seductive awareness anymore - I am aware of anything all the time.
 I can not be destracted or distract myself from forming sentences about either how humans feel, sleep, act or about me telling humans about my situation.
 I am in the most terrible state and also consider myself being traped between life and death. Nothing no drug, medicine, alcohol has any effect on me apart from a narcoses I had. It does not even have any effect on me if I eat or drink. So I went without drinking and eating for 11 days in the hospital and as I have a written report nothing happened even my blood samples where ok. I am currently not eating for 5 weeks and I am not even losing weight.
 Please help me, I am desperatly looking for someone to do research on me and I know that this is no Ufo sighting but I am really sure this is connected.
 I am in contact with the parapsychological institute in Freiburg but so fare nobody could help me in any way.
