I have been struggling for a few years now with a former manager at work who needed constant attention, took credit for some of my work, and then bullied me in front of my peers. One of my former teammates who showed concern for me now shows friendliness towards her and walks by me in the hall without looking at me or acknowledging my existence

I don’t have to work with them anymore but I do have to see them regularly and every time it brings back the hurt.
I looks like this is in the past but you have some unresolved feelings and maybe need some validation and resolution.
BullyUK is a website I used as a resource when I was dealing with workplace bullying, and the link takes you to the page regarding workplace bullying. I’m in the US and BullyOnlineUK was the most comprehensive site. Other than the personnel procedures and laws, most of the website should be helpful. I doubt you need that stuff anyway.
One thing I think is important is noting whether or not the behavior is bullying or, as others mentioned, a clash of personalities and you feeling like you were not liked and being liked is important to you. As TheLittleLady posted:
you don’t have to be friends, you have to be cordial and professional.

On the other hand, if it is simply a personality thing or immaturity (often in service industry jobs the supervisor is immature and has had no real training in managing people).
You simply be the grown up. Treat every co-worker with dignity, leave work at work, dont get in your own head, gain experience. In work, even if you work at the Vatican, you are going to work with some people where there is a clash. Learning how to keep it professional is a skill that will serve you for life.
Also, since is this in the past and you have a new manager you have a fresh start and at work I would let your work do the talking by doing your best there. I would not bring up a former manager to a current one; you may end up looking like a trouble maker.
If your experience does fit the definition of bullying, if you have experienced harm from it you make need some counseling or more. The challenge is if you do reach out you may get a counselor or therapist who is not well- versed in bullying so you might have to focus on the after -effects like PTSD, etc.
If it’s not bullying you still may need to process with a counselor or a good listener and share them the resources you use so they understand what you are trying to work through.
As far as you former teammate - remember she still needs to work with this person. Try not to put her in the middle; that’s not fair. She was supportive of you while in that environment and that is huge. If you do say hi, smile and don’t indicate that you are waiting for anything more than a return greeting. If she thinks you need to vent to her about Former Manager then she will probably avoid you. She’s probably trying to set a healthy boundary; respect it.
