I am a psychotherapist in private practice. It is a second career for me -- I started school for it in my late 40s after 14.5 years of being a stay at home mom. My second Masters degree.
I love it and find it extremely fulfilling and meaningful work. Being in private practice means that I'm in charge of my schedule, my income, etc. It is very flexible -- I still have a middle schooler at home. I also make a very good income.
The drawback here would be no health insurance/benefits. My husband gets insurance/benefits through his job so this set up works for us. Not sure what it will look like when he decides to retire. I guess we will have to buy health insurance. I intend to continue doing this work until I cannot do it due to physical or cognitive impairments. The other issue is that if I am sick or take time off, I am not earning money. So income relies on my ability to show up for work. But it all works out. I account for that when setting my fees, it isn't really a problem.
Good luck in figuring out your next steps!
