How can I get ahead?

Hey y'all, I am in a rough patch and need some advice and possibly some guidance. I (27M) and my fiancé (26F) are having financial struggles. We have a child together and want to give her a better life. Here is a little about our situation. I work full time in a government job, she just got out of college and has been trying unsuccessfully to re-enter the workforce for 6 months now due to Covid. My paycheck is high enough that we don't qualify for any government assistance, but not high enough to pay all the bills. We have cut out all of our streaming services except for Disney plus because of out daughter. We have canceled every subscription and have not eaten out at a restaurant in 4 months. I have been starving myself trying to make sure that they can eat. We buy only off brand and things on sale when possible. We have started to garden and I just renewed my hunting license to try to get more food. We are both over 30k in debt due to student loans, vehicle replacement, and low income. If anyone has any advice please tell me. I have tried going to churches, but they say I make too much. I'm severely depressed and I want to be happy again. I don't care about getting rich, I just want to be able to afford a happy meal every now and then for my daughter. I've tried odd jobs, but with my job and being a disabled veteran I don't have the time or physical ability to do a lot. I have been contemplating everything from starting an onlyfans to selling the house and moving us in with my parents in their 1 bedroom apartment.

Edit: I didn't expect to get so many replies this quickly. I am at work right now and I will reply to all comments as I get the opportunity.
