I could use some advice.

Hello, I am a 19 year old girl and I personally never had any issues with daydreaming until recently. I am aware that I have been daydreaming since I was about 10 but they never got in the way of my everyday tasks or social life. Nonetheless, when I was 13 I moved across the state and was diagnosed with anxiety. My life wasn't going as smoothly as it had been before I moved so I understood where the anxiety was coming from. This was a confusing point in my life because I didn't know how to deal with my anxiety. I was not on any medication or attending therapy. I had no friends or hobbies so I began to daydream excessively. This was not evident to me at the time, but I can see how maybe it could have been MD. Afterwards, things started looking up and I started to go to therapy, take medication and even got diagnosed and told that I actually had panic disorder as well as OCD. I graduated high school and moved away to go to college, during which time the daydreams continued but infrequently. I would not intentionally create these scenarios within my mind they would simply occur. For example if I was watching a video or movie that I enjoyed I would imagine how I would fit within what was happening. (What I would say, how I would react, etc..) Still though, this was not impacting my life much. My grades were fine, I was making friends and socializing and if I was in the middle of a daydream I could snap out of it when I was asked a question and answer with something that made sense. The problem I have started up during the pandemic. I am obviously back home and have a lot of free time. I don't leave my house because I fear getting someone inside my home sick so I really have no forms of distraction. During this time I stopped taking my medicine which might have been a huge mistake on my part but after suffering from multiple panic attacks I am back on it. Nevertheless, I have since been going through a depersonalization/derealization episode where I feel like I am not real. The maladaptive daydreaming is part of it as now, I am spending most of my time daydreaming and listening to music I feel would be the "soundtrack" to the story. I hate to think this but I am scared of going insane. Maybe because these recent daydreams are much more detailed and lengthy. I can spend hours daydreaming (even coming up with outfits I would wear??) and once I am out of the daydream I get confused and scared about how much time I just spent daydreaming. Since my daydreams have been more vivid, lengthy etc.. I have been having trouble organizing my thoughts and I've become extremely forgetful. I am aware that my daydreams are simply that, and I even try to schedule times to daydream so as to not disturb the time I spend with family or doing homework. Still, if I am doing any normal thing like making breakfast, I imagine the characters from my daydreams are around so I am basically inserting these characters into my real life. I have avoided acting out my daydreams in front of people so they only occur in my head. I was told by my therapist to avoid googling but unfortunately I did anyway.When I did my googling all that it could suggest was that I had schizophrenia. This really scared me and I don't know what to do about it. I am completely aware these scenarios are all fictional yet the fear I feel is horrible and paralyzing at times. Since then, whenever I come out of a daydream I remind myself of who I am and what my real life consists of (as depressing as it may be) even though I know all of this already. I could use some advice. Should I try to avoid these daydreams though it seems impossible? What should I be doing differently? Most importantly, am I actually going insane?
