Is my medication working?

I was diagnosed 2 years ago, and spent the last 2 years trying to accept and deal with this diagnosis. During the last 2 years I didn’t take my medication seriously, only taking it sporadically. When I finally decided to take it regularly, I realized it wasn’t working, so last month I started Fanapt. I’ve taken it every day for about a month now. The past week or so, I have been having all of these feelings of guilt, shame,embarrassment, regret, etc. my question is this: is it possible the reason I’m having all of these feelings now because my meditation is working? Has anyone else been through this?
