Help me understand my mental health symptoms

I got Alike to help me find out what I may be experiencing or to at least manage my symptoms. I don't have any diagnoses, my only "proof" are online tests and accounts from family who believe I may have ADHD. I'm not looking for a diagnosis, I'm looking to understand my symptoms and I. I may not be going about my mental health the right way, but this is the only way I can as of right now, so, please, if you can relate to any of my symptoms let me know(or let me know if they even ARE symptoms) -difficulty concentrating -occasional out of body experiences -times when I feel I'm like somebody else whose observing me -trouble going to sleep at a good time -All my dreams have disturbing undertones -Daydreaming or just sitting and staring -Trouble with motivation, or just getting my body to respond -Thinking everyone hates me -Struggling to be myself
