My dad used to call me a useless piece of shit and that I should hang myself because I'm just a waste of his money; when I was a child it was fine, but over time it started to dig into my brain and eventually I developed an inferiority complex and had thoughts of suicide. If I had left him earlier in life then this wouldn't have happened.

Do not attempt to tolerate insults, you must be proactive in resolving it otherwise it will manifest in adverse effects later on.
