True that, also the notice period I'm contractually obliged to follow is in the phase where I could leave at any moment, whereas waiting for the trial phase to be over would force me to wait 6 months to leave.

My fear is that, coming from a similarly dysfunctional place, I'll just put in hopes and efforts for a better workplace and end up somewhere even worse, at which point I'll have to slow down in order not to change 3 jobs in such a small amount of time.

Also, sometimes I just feel ungrateful for whining this much, especially considering I have a family (not my own, mind you) to support and cannot allow myself to simply be without a job (and a well paying one at that) for long periods of time - I would love to have some objective measures for saying the role is not worth it, but of course that is not feasible in reality, and that deeply bothers me.
