Early 30s - is a psych PhD career change totally insane?

Hello!

I'm seeking some career advice regarding an unconventional career change. I'm currently a professional musician - well, I was before Covid - and I'm strongly considering a career change to either clinical psychology or counseling at the Master's degree level.

My primary question is whether or not getting a PhD in clinical psych would be totally insane, or whether it's possible for me at this stage in life - because I'm turning 33 next month. Due to some chronic pain issues, I'm not able to continue a full-time music performance career. Additionally, I'm at an age where I'm needing to think about a more stable (and lucrative) career. While it may seem strange to be contemplating this path at my age, it's fairly common for professional musicians to have a "come to Jesus" moment in the early 30s and start a new career. I have a lot of friends my age who have started on the path to become nurses, lawyers, computer programmers, etc. I've always been extremely interested in psychology and everything having to do with the mind, and have a strong desire to help people struggling with mental and emotional disorders. Psychology/counseling was always what I thought I'd do "if I hadn't become a musician."

As an undergrad, I completed about 3/4ths of the requirements for a double major in psychology. At the time, I decided I needed to just focus on music all the way, and dropped the double major. I could return to my undergrad college and finish the psychology degree in one year, with 50% off tuition as a returning student. This means that realistically, factoring in a year for studying, gaining more research experience, etc., I'd probably be starting a PhD program in the Fall of 2023 at the earliest, if I were to get accepted. This means, of course, I wouldn't be actually entering the field until age 40 at the earliest.

So: why am I even considering a PhD, as opposed to a Master's in counseling?

-The ability to do research

-The ability to teach at the college/university level as a professor

-Higher salary (that's a big one)

-Fully-funded grad program with stipend, vs. shelling out lots of money for a Master's program

-Just being more rigorously-trained, and grounded in scientific/evidence-based theory

​

I'd say the biggest factor for me at this point is money. From the research I've done, I'm under the impression that clinical psychologists can make much more money in private practice than counselors/therapists in private practice (and private practice is what I'm mostly interested in). I do also have an interest in research and teaching, for sure, but it's not the most important thing for me. If it were the case that I could make nearly the same salary as a therapist at the Master's level, I probably wouldn't be considering such a time sacrifice of the PhD just to be able to do research and teach at a college.

Thanks for any advice & insight!
