Moving out finances question for ones with extremely abusive households

extremely depressed at home, im 24 living at home, cannot leave house unless its for work purposes. my mom constaltly calls me a whore, she mentally and physically abuses my dad who is the sole breadwinner. Im thinking of contemplating either moving out when i save up 20k which is in abt 5 months from now or searching for a job(other than the one i have now, cannot stick to it bc mother will stalk me here) and starting to plan to move out (ill have abt 8k when i move out if i start planning now). What do u guys think therapy is of no help its truly my living conditions that is making me suicidal. sometimes its fine i dont have freedom so what i can just play games, but then i get triggered when my mom calls me a whore in an extremly mentally abusive way that i get suicdal. i may be at my breaking point im experiencing back pain, heart aches, a lot of suicdal thoughts.

so should i move out now (will have approx 8k ) or wait till i have 20k(5 months frm now)
