I am sorry to hear that you are in this situation. It seems very difficult.

Whatever recommendations a therapist might make, it is always your choice to take them or not. My own perspective, for whatever it is worth, is that my therapist has been mentioning a specific change that he thinks I should make in my life, at irregular intervals for over two years now; I can see his point, but am not prepared to make the change. That is my choice, and therapy has been and is immensely valuable for me despite that choice.

What a good therapist can help you do is identify and recognise areas where you could improve your life without making sweeping changes that you are not prepared to make. And it might be useful to have an intelligent professional to discuss things with, such as how to make your business run more smoothly, or how to cope with your feelings around your mother's and brother's situation.

I don't think there can be any harm in at least trying it out.
