Will this make it worse for my kid?

I (36) have two kids and my oldest (8F) is battling depression and anxiety, as am I. Unlike me, however, she has thoughts of self harm. She's very close to me, we homeschool and she has no desire to go back to public school. I recently decided to go back to school for psychology and eventual med school to become a child psychiatrist. I plan on starting a non profit to benefit child mental health. My hesitation is, I asked her how she felt about me going to med school and she's not too happy about that because they may mean they'll have to go to school for a few years or I just won't be around as much. This would be great for us financially (though she'll be almost grown by the time I'm done) and it will allow me to work remotely and help young children and their families. I now fear gif I start this journey that it will make things worse for her. I obviously don't want her mental health to be affected by my decisions. Any advice?
