I don't come here to claim I can relate to basically any of this but both myself and a lot of other people around my age (I'm 28) that I know are going through effectively a "restart" somehow in their careers/relationships whatever after some kind of false start.
in my case it was a divorce, in my friend's it was her career, in another's it was like three different things, anyway I can't relate directly but I'm sorry for the parts of this that are hard, and thrilled for you to move forward and find the good shit, as yourself
