hmm I agree with you and disagree w/ your mother.
I am thinking about studying Psychology for a living as well. Ive taken 2 psychology classes so far, and if anything it has HELPED tremendously. A lot of the principles (even if they dont directly relate to anxiety) I can apply to things I see in my life on a daily basis.
It's definitely not hurt me in any way. Ive never known a situation where being educated on something can HURTyou.
If your mom doesnt like the idea of you becoming a psychologist or doesnt think you can become one, look at Lucinda Bassett (
www.stresscenter.com ) She had an anxiety disorder and is now helping millions of people over come it. Shes living proof.
I look at my anxiety disorder as something that will one day help me with something else in my life. Like i look at all life's instances as building blocks. They all mean something and have significance. I think that if we overcome anxiety having experienced it, we could use that to help others. Things happen for reasons, and that could be your reason. If psychology interests you, go for it!! Do what YOU love to do
