I was in a similar space about a year ago following, at least how I felt about, a fairly rapid taper. It wasn't a switch, but it left me in a place where I took a leave from from and then again took a leave this year to manage the help with a more intense intervention. Have you tried journaling to get some feelings out on paper in a more concrete way instead of having them race through your head? That was my experience and journaling has helped. Have you altered your diet at all? I learned about opposite to emotion action as a form of therapy. Even if you can take a small walk when your mind/body are telling you no, maybe it will be a small victory for you. Did you taper off or was this just a switch? Maybe have someone on your support team (family, friend, etc.) write down a list of questions for you to ask your therapist and maybe attend the next appointment with you as an advocate. Will pray for you.
