sucks that you are getting abuse, especially from a family member. They are supposed to be the ones always in our corner no matter what.
To answer your question, no, my family is quite supportive. In fact, I am the one who is sometimes cold to them and keep them at a distance.
However, It wasn't always like this growing up. You see, I have two brothers, one older and one twin (non-identical). We all suffer from bipolar disorder with varying degrees. Luckily, I have had the easiest time with it, relative to my brothers. Anyway, back on track, my brothers were very toxic when we were struggling, angsty teenagers. I remember always dreading any outing with friends because I knew my twin brother would ruin the atmosphere by being insulting, brash, paranoid, and overall quite toxic to our friends, which we shared. He would always get into fights with people over the most mundane honeysuckle. I don't have an exact memory, I think I blocked that part of my life up outta my active memory. He would always accuse people of conspiring against him and talking trash about him, even our parents weren't spared that behaviour, that's how deep his paranoia went. I remember harbouring this inner hatred for him. Hatred that I never expressed for fear of the effect it might have on him and our family. I still feel traces of this hatred deep inside me.
My older brother, on the other hand, was more chill....BUT, he had a lot of demons. He was the first in our family to start drinking and smoking and when my parents would talk to him about his behaviour he would lash out in disturbing ways. Suffice it to say, one time, he said he would slit my mother's throat.
Anyway, they are much better now that they are on their meds so all's well that ends well I guess.
