Unnecessary Sliding Genioplasty? Bottom lip not functioning like before. 2 month post op. Help and advice needed.

I am devastated with the results. My chin is too prominate and tilted up, causing my lower face to look short with a large step off felt on the right. My bottom lip is not functioning properly, it has rolled in and gotten smaller. I am unable to blot my lips or chew with my mouth closed and my lips do not meet at rest without force. I'm seriously considering a reversal asap, but I am scared of doing more harm and I don't know if it's too soon. Please help, I am sick of crying over this.
