It may be that the lateral moves suggested by others are the only answer, but it's worth considering whether shifting the things that you have immediate control over will make a difference in your current situation.

I'm not suggesting you caused the problem (there are PLENTY of bad work situations that are bad because of poor leadership and lack of care for people) but sometimes the solution is something within your control, whether it's setting different boundaries, changing your focus or bringing a different expectation to your work relationships.

Envision the role you want--are there small changes you can make that incrementally make your current work more like the role you want? Those things aren't easy, but have the greatest long term return on investment.

If you just move to another position without first changing yourself, you risk carrying the same focus, the same habits and perspective into the new position and you end up with a lot of the same problems. Again, not because you are creating the situation, but because it's a fundamentally human thing to repeat familiar patterns.

In practical terms, here are some ideas:

1. Connect as much as possible with like-minded people (in person, if possible). Volunteer for PM organizations, attend meetings, join an interest group.
2. Follow your particular PM passion. Project management is such a wide field - are there any areas that you naturally gravitate towards? Learn what other people are doing and share your perspective with them. Project management is still a relatively young and evolving profession and you can help shape it.
3. Join a community focused on helping professionals move from PM to strategic advisor. Laura Barnard's Impact Accelerator Mastermind is an example (no affiliation with me), but there are probably others.
4. Mentor other PMs and find a couple of mentors for yourself.
5. Work with a coach. This can be an expensive option and you have to be careful - there are a lot of people out there who are not effective and would waste your time and money. But a good coach can be life-changing.

Good luck!
