I had very unpleasant experience with depersonalisation and derealisation few months ago. I went to psychologist because of this, it short term helped, because on or two sessions aren’t a lot.  At one time, I thought it’s all caused by brain tumor or something. I’ve never dealt with something I would consider panic attack, but broken heart and a lot of worry, that is me every day. Don’t worry about the broken heart thing, it’s getting better.
So for some time now, I’ve been dealing with much more of apathy, social withdrawal, but I really don’t mind going out, it is just complicated, because my bestfriends are dating. 
And for two months or more, I have this worry of becoming psychotic or, better said, being in prodromal schizophrenia. I spend a lot of time googling these things and doing typical stuff I shouldn’t do. My psychologist already said to me, that it is not happening, but I really can’t think normaly about anything.
I somehow feel able to give up on this worry, but I keep telling myself, I have to be afraid and introspect, or I’ll lose control, which I already feel like losing.
I really have hard time remembering short term stuff, sometimes I can’t remember where I’ve been on vacation two years ago, or what was my life like, before the dp/dr started(it also somehow went away).
Ay this apathy really is too much for me. I can’t enjoy or empathise with anything. But actually, these worries tend to go away, when I do something really good(cinema with boys etc.)

So my question is: anybody relates? Is it possible I am developing schizophrenia, or is it just overthinking and something I shouldn’t worry about? I am just scared of losing insight, I recently feel like I can’t even see these weird thoughts as weird.

Thanks a lot? (I am 15 and male)
