Need help with loans are twice as much I took out

I only took $50,000 and now 6years later my loans are $167,000 because of interest. I am a single mother of two and I take fully care of my mom with no help .she lives with me and my kids and gets no help because she is not disabled or of the age of. 65 but she is very depressed and doesn’t get out since she lost her job 7 years ago. I have no help with my kids so my salary covers us 4 people with nothing left. I tried to do a student payment plan but it is still very expensive when I have to take care of my family. I just wanted the loans back to what I took out so I can pay that down it is not fair they more the doubled my loans
