Anxiety meds & Breastfeeding

I have my pp appointment later and I'm torn. I want so badly to get my anxiety under control but I'm worried about taking meds while breastfeeding. The anxiety is nothing new I've just been living with it but it is worse now with everything that comes along with having children. I don't know if I should continue to deal until we're finished breastfeeding or discuss it with my ob now. I know there are meds that are deemed safe but I can't shake the thought of somehow altering my perfectly happy/healthy baby. There are many instances where doctors say something is safe but later discover they were wrong. I will always wonder if I'm the cause for any changes in my child now or in the future 😓
