I'm not going to diagnose anyone but I had a bf once who was the same in many ways - He was primarily Dependent PD with entitlement, secondarily Borderline

My personal opinion is OP is not ready for independent life (no pun intended again). Not ready for a normal full time job

Ready maybe after a few years of intensive psychotherapy and such, or for a special job environment

OP only managed until now because that manager gave special support. But it should never have been the manager doing that, it should have been the years of intensive psychotherapy done first.

We are not going to be able to help here.

Managers and the like either at work will not be able to help you, OP. They will always run out of energy after a while because it just plain isn't sustainable by anyone, no matter how well-meaning, as it isn't a therapy environment with the right boundaries and background support for the therapist as well. So OP, you are just going to hurt yourself further that way. Be patient and wait until you get into therapy.
