How to gain back lost motivation?

I have worked at a brothel in Sydney Australia for the past 2 years, and it started out really fun! I made a lot of money but I will say definently partied way way too much.

Due to medication I’m in I’ve had to scale the drugs and alcohol right back. honestly I was keeping up for a while there working sober, but I honestly just dread every booking now. I feel I have nothing to talk about with these men cause I just have low key lost a lot of respect for so many of them and I am struggling to brush it off and act like I enjoy it.

I simply just feel I’m not keeping up with everyone here lately. I also have just started university and they won’t let me do a 1x9 hour shift a week, as we have to do 2.

I’d love advice on how to have fun again with this work while sober and regain the excitement when I started 2 years ago.
