I could use some advice. I wish I could support myself but I don't know how.
Why can't you support yourself?
I don't have enough money to take care of myself
You should get a job that pays better if you are unable to support yourself. You are expected to be able to pay your own rent and your own bills. Others will think that you are dependent.
The pay is too low and I can't live on my own.
You can see if you can find a second job or something in the gig economy. You will find something to make it work.
