I'm thinking I should quit my PhD

I read a lot of advice about choosing a PhD, and having a good advisor was important to me.  I spent some time with mine before I joined and I decided she was the right person, and I liked that I was expected to publish a lot and there seemed to be a lot of support.

When I started she vanished almost immediately.  I tried asking her for a weekly meeting, but she just blew me off.  So I've basically been on my own for several months with just google.  The project I'm working on has also turned out to be different than what I was originally told, and I feel like I've been lied to.

Then I found out that the group of five others I joined was actually three: one was a professor emeritus who is never around and one had just left.  And worse, the other two are leaving in the next couple of months, and there are no grants to hire anyone new.  So it'll likely be just two of us for most of my PhD.

Worst of all, she has no contacts beyond a couple of former PhD students, and she's very opposed to me going to conferences or to trying to find collaborations.  I've brought it up several times and I get told no every time.  She has alienated everyone in the field and the university.  The woman who is leaving has nowhere to go because no one likes dealing with us.  She told me last week she'll likely be waiting tables in six months.

I've lost all motivation to study.  I've been considering this for a couple of weeks now, and I think that it's best that I quit now before I'm too deep.  I guess I just want to write it all out and have someone impartial read it, have you either confirm or deny my worries, because right now I think it's highly unlikely I will find a postdoc.

To me that's a major red flag. PhD supervisors should be train and mentor their students to enter academia. Discouraging them from networking or presenting their research does the opposite of that. Unless she is protecting you because you're not ready to present, or something like that. But if that is the case she should be upfront about that and work with you to improve your presentation/research skills.
