We are in need of a lawnmower

I had brought a $200 lawn mower for it to just not cut my yard 2 times no one can help me I've tried to fix its just no good. I have been spraying my yard with grass killer that runs about 80$ a month and that only when I can afford it off a 568$ monthly check from the government. Due to Im still having trouble with treatment and medicine from all the trauma and the lost of me and my kids / mothers home and her. I went into a mental meltdown and no one would help till 2025 of April they are only helping my mental. And even told me to try and do this
