single moms???

So I am a single mom. I work full time and dont qualify for any state assistance because I make too much. Literally right above the income guidelines. My son is 6 months old. Lately I've been extremely stressed. I've been struggling with milk supply and in turn struggling with my work performance because I've been needing to pump more often. Then I'm paying 1300 a month for child care on top of every other bill. My sons dad sends $200 a month and isn't any help other than that. My son has been sick on and off a lot the past month or so and I've used a good amount of my vacation time to compensate the time away from work. I really just needed to vent. I'm beyond tired. Nothing I'm doing is seeming to work and idk what to do anymore. Really mentally exhausted at this point.
