I’m considering switching to the GRE since I think it’ll be better on my nerves - without the algorithm and being able to skip questions. I took a practice exam and got a 550 GMAT equivalent.
If you are referring to generalized exam anxiety, then you would be better placed in first trying to address it. Anxiety is real and is a common phenomenon. It can derail any activity.
Is your anxiety only related to the adaptive and non-skippable nature of the GMAT test? That's what you seem to be referring to. Although that is possible, I would advise that you address the abpve first and not assume that your experience is related only to the GMAT.
Many schools now accept the GRE, but there are some differences in discipline requirements, e.g., in non-MBA graduate programs. In general, you will be alright but it is still wise to check with specific programs.
