If your mother's toxicity is the root cause of your problems or a major contributing factor then it's probably better to wait until you're feeling strong enough to stick to strong boundaries. I don't necessarily believe we should totally cut ties with people we deem toxic if we can remain mindful of the toxic traits we can learn a lot about ourselves by interacting with them? Like, how do they try to manipulate me, how has it conditioned me, which toxic traits have I inherited?

It's natural that you want your mum to love you and care about you so you'll always want to give her another chance no matter what, because you are a good person and believe in the good in others, which sometimes may not exist or can't be accessed because of their own trauma.
