How do you survive on a waitress income?!

I have been a waitress for many years. And I used to be able to live on tips alone and have extra money left over to go on vacation etc. I used to save most of the money I made from my tips account and I was able to afford a lot of things. I used to take home around 150-200 per day. I’m not able to afford these things anymore. It is becoming to expensive to function. A lot of my money used to go to savings and now I’m using it for my daily needs and not able to afford anything else. Another thing I noticed, it’s become very expensive to even make money at this job. Gas, car maintenance, the tips have slowed down. I’m very stressed over this. I’m not sure how to afford living like this. It’s become very hard. How do you survive on waitressing money!! I’m very in need of help right now.
