Hi, Thetruthhurts. You are correct, of course, no person can change your circumstances.
What CAN change, many times, is the way we FEEL about our circumstances.
Let me first say that I have experience with both psychiatrists and psychologists. The difference between the two is that psychiatrists can prescribe medications and psychologists are limited to "the talking cure."
One thing I was slow to realize was that the doctor can't "fix" problems without the participation of the patient. One of the first things the patient has to deal with is their EXPECTATIONS. As an extreme example, if your foot has been amputated, no psychiatrist or psychologist or mediation can give you your foot back.
They can help you see ways to change your feelings about your circumstances from one of "I'm a victim who didn't deserve this." To "this happened to me, and I survived it."
As with any doctor, you need to find one you feel comfortable with. I wish you success in your journey.
