Struggle of being a student and stay at home mom

I don't really know what to say but I need real legit, remote jobs otherwise Im losing it all. People seem to prey on my hope. I keep hoping I will run into something while I search instead they make me work for hours to earn, when I'm done they expect me to pay $150 to earn, where do I even dream of getting this 150. I have a 6day old baby girl and an 8 year old little boy. I have never begged or asked anyone for their money, I keep trying to get work. Unfortunately I don't have seem not to be lucky e to even get one real one. As I speak I worked all night, last night re typing, proofreading for some agency, they promised to pay $1500, where is it now, I have to pay $150 to get an IMF code. I feel tortured and used. Please help me get atleast one remote job.
