Lip Sagging. What has happened? How can I treat this? (Photo)

I am a 42 year old female. My lips have started to downturn and sag in the last several months. They droop when I lay on my side or lean to the side. They also jiggle when I work out or run. What in the world has happened? They used to be firm and cute and perky. I was given Botox injections in my dao muscle and chin 7 weeks ago and it make it much worse.
