\[ firstly, sorry for any grammatical mistakes, English isn't my first language \]

So I've been experiencing this for as long every once in a while, as I can remember.

I sometimes feel like time is moving slow, but not time in particular, but things, sounds, movements, thoughts, everything. 

It's almost like putting a video on 0.25 speed.

The feeling fades after few minutes, but it calms me and annoys me at the same time.

Yesterday, I googled it, and it said that it's a symptom for anxiety disorder. 

I didn't really believe it 100%, but since I'm experiencing other 'symptoms' of this disorder ( or that's what google said) , therapy is quite expensive, and 'what if I'm just attention seeking, yk?' I will waste my parents money for no reason .. 

I thought I could get some advice from people who actually struggle with the disorder, maybe information .. anything.

Is anyone experiencing the 'everything moving slow' thing ? are there any obvious or not so obvious symptoms ?
