About whether I should call/text a hotline

Alright so taking this is a really HUGE step for me and I thank that friend here for telling me to seek help. And its gonna be partly a long post. 

Its about whether I should call/text a hotline by youse all opinion regarding what I ve been through and still going.

I live in a really toxic household. Misunderstandings, insults and fights are common here. 

My parents never really believe me, support me or anything like that. They are constantly fighting and yelling and calling each other names. My father is the worst. He keeps telling my mom she would be nothing without him.

I want to like generally speak and not get into too much details. I have undiagnosed ADHD POTS PTSD and more because my parents dont believe me. Never did. They say i lie or blame it into the phone.

My father is emotionally abusive. My mom is too but my dad is the worst at this. He keeps telling me some stuff about women that I really cannot take anymore and I really dont know what to believe.

His opinion about women is...weird. He tells me that women are weaker than men that men will always rule over women. He tells me that women are let into the jobs by men because they want to have something beautiful to look at, touch etc (I dont want to get into the details he said). He told me that money spent on women going to college is a waste of money.

I have constant stress, anxiety, nail biting and derealization/depersonalization disorder. 

I have gone through a phase in my life at the first and second grade of elementary school that I used to pull my hair. Also I went through anorexia sometime at elementary school again. I never understood till now that it was all caused by the toxic household. 

Anorexia keeps coming back to me sometimes and I really dont like it because last time I was one step before entering hospital.

I have Undiagnosed POTS and ADHD as I already said. My life is not easy. 

I want to say here thst I never had any proper help by them. They always criticized me, threatened me, insulted me and never actually helped. They told me i m lying and I should stop this like it was magically too easy to stop anorexia, hair pulling, nail biting. When I told them about my POTS symptoms they mocked me telling me I m lying and about ADHD? They blame the phone. Also my mom believed my POTS symptoms where because of an eyesight problem I went to a doctor for it she saw me eyes told me that yes they are a bit bad but all those symptoms aren't caused by this but guess what? They never did anything else about it.

My brother is becoming like my father and my sister is actually telling me she doesnt care because she ll leave in 1 2 years from the house. 

There are really many more things going on. I have sleeping problems as well. I dont know what to do. I used to self harm. There are really many more things to say but I m getting overwhelmed right now.

So I need your opinion on the matter any things you'd like to suggest me and if possible tell me: should I call/text a hotline yes or no? Am I just overreacting? I need some answers. 

Thank you for reading this.
