When Everyone Says You're NOT doing a good job raising your child

What do you do when everyone in your family feels and says that you are not doing a good job of raising your child? As a single mother with a 5 year old who is throwing tantrums and a 7 month old, I know I have my short comings. I am the sole breadwinner for my family. I feared having children because I know I'm won't be a good enough mother. And now, it is all coming true.

As much as I know phone use is not good for kids, my older child is used to it because it was introduced by my domestic helper in the past to feed him. It can get difficult to manage him at times without the phone and everyone is making seem like it's my fault.

I love both my kids, especially the elser one for his good nature. Just don't know how to manage him. All the textbook answers on parenting don't really work.

I don't know if I have the strength in me to pull through this. I wish I can be alone with my 2 children but it is not reslistic.
