When was the last time you were consistently in therapy Heartstringz? Did you ever find a therapist you could connect with?
I don't have any direct experience with anxiety meds however I would think walking into a doctors and demanding them would put up a big red flag which would make a doctor extra hesitant to prescribe them.
Try going to a doctor, talking about your situation, talk about what you've tried in the past and how it worked. Then see if the conversation moves towards meds. It might take a couple of appointments and/or some therapy first. If it does take time for the doctors to prescribe you something there's probably a good reason for it.
You've been having a hard time since bub was born - hope things improve soon. Xx
