Let your therapist know how you feel about meds. Let the psychiatrist (if you choose to go) know how you feel about meds.
It's ok to be nervous or scared about going on meds. I remember hating being on them because I didn't feel like I should have to take a pill just to function. I wanted to stop. But instead, I let the medicine continue to do it's job and function as my scaffolding as I got my life together. Eventually I weaned off and have been med free for nearly a year now. I do take supplements to help me though.
