I'm not sure what I should do, I had a dream and my therapist was in my dream, by the way the dream was NOT sexual. I am wondering if I should tell him about my dream or not????

Would love to help someone solve their mind related issues.

Is it abonormal that whenever I gain interest in a certain show or game that all of a sudden I drop literally all my other interests and focus mainly on one character in that series/game. It gets so bad that I'll actually imagine myself being in a relationship with them and also adopt most of not all of their traits and pretend I've always acted like that when in reality I was different before hand. But then again that could've been another character. I've been doing this for near 10 years so I don't even know who I am anymore. It's frustrating and I'm honestly concerned as it's nearly ended friendships in the past. In order to stop it, I've tryed asking myself am I doing this as me or as the character. This has proved unsuccessful as it just makes me paranoid that I'm being a character when I do something the same way I'd imagine the character doing something. It could be the most mundane task ever and I'll still be paranoid that I'm not me but someone else.

I've had dp/dr, emphasis on the DR, for about 4-5 months. I'm 19 years old. I know I got it after a visit to the ER a few months ago for chest pains, which turned out to be acid reflux. On top of that, I was and still am having migraines and very intense sharp pains in my head. I do have an appt with a neurologist.
Anyway, the world has felt completely fake and dreamy to me starting a few weeks or days after that visit to the hospital. I know my anxiety spiked an extraordinary amount, the worst it's ever been. I've been suffering from panic attacks since I was about 9 or 10 -- I remember sort of feeling derealized once back then too. However I didn't process it as intensely, so it went away quickly, plus I was young and my mind was occupied almost always.
I'm just terrified at the moment, because I've always been tortured by existential thoughts to begin with, but having dp/dr makes them so much worse. Unbearably worse -- they would send me into a spiralling panic where I'd just cry and cry for days on end, and I hate being alone with my thoughts -- I've been sleeping in my mom's bed This dreamy feeling is so real, I can't always convince myself that I'm not dreaming, or that the world ISN'T fake. And that is what's been getting worse. It's like my brain is convincing me everything is fake,oh well. I feel completely hopeless at this point.
My panic attacks lately have been about how I can't believe I'm going through this. I can't believe this is actually happening, so my brain says "it's not" and now I'm fk'd.
Will everything ever feel real again?
Will I ever enjoy life again?
I think another reason I'm stuck in this is because I'm not in school, and I'm unemployed, There's only so much I can do to get a job. I've applied everywhere.
I have memory problems, panic attacks in which I feel as if I've dropped acid, and the world feels so fake I can't believe it's not. Writing all this down/talking about it does not help one bit. I've purchased 2 books in the mail that are supposed to help me--one should come tomorrow, so wish me luck xx
This is one fk'd up anxiety symptom.
(Hard to process it even is one anymore)
