Feeling lack related to money

I am a school social worker in a very impoverished city. My job is very stressful but I really feel like I’m making a difference to the kids I work with and feel like its my true calling. My husband is a teacher in the same district and he also really enjoys his job. We have three children, 11, 8 and 4. Two of the children are in competitive gymnastics which equals about $10, 000 a year with monthly fees/booster club/meet fees etc. One of the issues that I am currently struggling with is regard to my feelings/thoughts around money and lack thereof. I realize how fortunate I am in so many ways but struggle with lack of money. On weekends and weeks off instead of going places many days my husband is doing side painting jobs etc. We struggle every month to pay our bills and don’t have the money to go on vacations or day trips like I see so many of my friends regularly doing. Its very frustrating. I find that I am often buffering with alcohol or food when u feel jealous or bored with my life. I am working on that through journaling and writing. I really want to be open to finding ways to create money but I’m not sure where to go from here.
