So these symptoms started at around age 12-13 ish and they've slowly gotten worse
Im rlly self aware but it still took me a bit of time to realize
So basically there are days it's bad and days it's not so bad, on days it's bad I can't understand or comprehend what ppl r saying to me, I also will go mute, get overloaded rlly easily and will have a mental episode over small things like I didn't like the feeling of something or sounds and just small everyday stuff that I didn't have mental episodes a out before, I've also started to get ticks, there are days where my brain just doesn't feel right and everything feels wrong and I can't rlly understand anything not even english which is my only language other than a little sign language that I've had to pick up in order to talk cause otherwise it feels like my vocal chords got cut,  I end up feeling very vulnerable and sometimes it gets bad due to stress or a situation that just triggers it and when that happens my brain completely switches and I now don't understand much, everything is confusing and I get very many panic attacks when my brain gets like this
I've had mental breakdowns and mental episodes, my mental episodes are different form my mental breakdowns, in my mental episodes I tend to curl my hands into fists and put them at the sides of my head with a lot of pressure, or sometimes instead of just holding them at the side if my head I'll start hitting my head in the same spot I'd hold my hands, I'll tightly close my eyes my breathing is quick and I can't talk and I'm not crying most the time my episodes are from getting overwhelmed
Ik there is more stuff but every time I try talking about it, it ends up being too hard time explain and I can't remember the rest rn 
I'm just wondering if anyone knows what I could have that makes my brain switch like this, I don't have the money nor ability to get tested for a bunch of things and I just really need to have an idea I'm not asking for a diagnoses I'm asking for ideas on what it might be so I have a place to start cause rn I have no clue
