55 years after multiple concussions

I'm 55 years old and i have not been able to find anybody in my life i could ask for help. I received my first concussion when i was less than 1 month old and my second when i was 7 years old and my third when i was 10 years old. i have received more labels than i can count including emotionally handy capped and social maladjusted. Ive also been diagnosed with Bipolar with IED and other Labels since i was a child. I grew up having gran mal seizures and migraine headaches. and have had weird headaches since and I've had episodes of snapping out and breaking things and destroying my things and ruining all of my relationships in my life. I've been begging for help with these problems all my life and been accused of lying and being a junkie because the Dr thought i was asking for help with my headaches meant i was asking for drugs so she kicked me out of her office. But I've been told by several Dr.s that headaches are normal but my question was and is still is are daily headaches normal to the point that i have problems thinking and my energy levels and in the toilet. And i have a bad problem of snapping out and destroying all my things. And destroying all my relationships with everybody I've known in life. I've begged and begged for help but I've never received any help. And now I'm at a point that i cant keep down a job and i don't know what to do because I'm not asking for a check or free money and i just want these problems to go away. I already know i wont receive any help from this because since i don't have a job i have no insurance and no Drs i can ask for help to be kicked out of yet again. so yet again ill not receive any help but i keep trying to ask for it. until the end. I could go on and on. I'm scared that as i get older i will only get worse at flipping out and my memory is getting worse and worse. And i don't know how weak i can feel before i just cant do anything anymore. Thank You.
