Well you can take small steps like take an on line course and do some volunteer work in a field you may want to go into, and see how it goes.
I have a degree and a job that can be stressful in social work, but there are ways you can keep your stress down also, that is something you can control to some extent. It helps to have the support of family to help you when you get stressed. My husband will clean and make meals if I tell him I am having a difficult time. I also exercise like crazy that keeps down that stress level, and helps with sleep.
So if you feel ready to try go for it, don't take on too much too fast, and find ways to manage the stress when it comes.
