And... at this stage, I have reached out to several people from my last job to either get a recommendation for my LI profile, or to network.

Not ONE person has responded to me, except for my boss, who only replied to my 1st email.

It's maybe inappropriate for me to reach out to these people,. after having been let go, but I had hoped there would be some amount of compassion and support for me in my plight.

And not one from that company will agree to write me any kind of positive remarks... I was very engaged in the work, I always met every deadline, and I carried a positive attitude and a team player mentality in that job.

Couldn't someone write some nice words for me as a favor?

I am pretty taken aback by the lack of response and by the unwillingness to help me.

It's awful... and I am feeling rejected as a result of the ghosting. It's a terrible feeling.
