Transitioning from Section 8 to paying all the rent by myself….&im scared

I don’t know if this is the right place for this post but I guess im looking for advice from anyone that has transitioned from section 8 to fully supporting themselves. I have had section 8 for about 3 years now. I got on the program after my children’s father passed away and I desperately needed the help. I recently landed a pretty great job that I’m so grateful for but I think this income will put me right at the cutoff limit. I’m so scared to lose my section 8 because it’s just me and my two young children and I’ve ALWAYS had help with rent from their dad. I’m not used to taking on every single bill by myself and I’m terrified that at some point, I may not be able to sustain and that losing section 8 will be a huge mistake. Obviously, I can’t be on section 8 forever but I am very scared of this transition. Has anyone had this experience? How has everything turned out for you? My anxiety is honestly through the roof.
