I'm failing and falling apart

I'm literally having a mental breakdown. Between my living arrangement; struggling to find my own place and failing, finances and STBX husband dropping child support lower and lower every week when hes weekly pay and I'm only biweekly, and now him allowing his parents go get him an attorney knowing damn well I cannot afford one and instead of going contested with agreements and paperwork done together, they're going uncontested claiming I canceled twice to sit down with them. Which is false seeing as how no one communicates with me😔

I think I'm at my breaking point.
