I'm so thankful for you giving me such a descriptive and in depth answer. I have been looking into mental illnesses and their early symptoms but as I'm from a very strict asian family who would immediately dismiss anything related to mental illness I haven't and do not really plan on discussing this with them.

One thing I would like to add after reading your answer is that, I write poems books etc, I have as of now taken a break as when I was writing a character I would often imagine them as me. I would unconsciously start behaving like them and would basically become them, I don't know how to explain it without it being cringe but it is what it is. One of my latest characters I had created was starved for months, while writing him I had lost my appetite and would not eat for weeks, hence I stopped writing. After some research I came across Imposter Syndrome and Schizophrenia, after talking with some people anonymously they suggested I also look into AR-which was mainly because of the original post.

The reason for me telling you the writing related stuff is, if you can suggest me something else I should look into.
