Hi and welcome to GMAT Club!
Sorry about the hassle with the PsyD. That is super annoying to get dismissed. Sorry!
Well, for MBA, you would usually need at least 2 years of Full Time work experience. Do you have that potentially?
The reason you do want Work Experience is because you build on top of that so an MBA is not really a good fit if you don't. A Master's may be a much better option and easier to transition into and only 1 year degree.
However, with both MBA and Masters, you want to have an idea of what you want to do and why you need these degrees. They require a harsh application process and then a few years of paying very high tuition bills so need to have a pretty good idea of what you are going to do with that degree.
P.S. There are no issues with not having business background. MBA is very friendly to non-business folks and Masters kind of depends... but it is all about what you want to do with your degree at the end of the day. If you don't have a job and you are trying to get a degree in Business with the hope of finding a job easier down the road, I am not sure that will be the case. Masters may work as long as you have stellar grades and you are driven and passionate and then you can get an analyst role in tech or finance perhaps. However, if you are struggling to find a job right now, a Masters or an MBA are not going to super-charge you and make you super attractive, it will be more like a new wrapper for the same product. 🤷♂️
