Hello! Trying to heal

Hi. I am 14 years old and I am trying to heal from a pretty bad childhood. I won´t put all of the details here, but when I was 10 I was thinking of suicide and even attempted it a couple of times. I told my mom about this at the time and she brushed me off. That was really damaging and I am trying to heal from the mental pain that inflicted. I know that I will never fully be healed until I am away from her, but I feel like I am crawling out of the hole that she digged.
