I'm going to push away the person who's been here for me through a lot because I know I'm wasting their time
What did this person do to help you?
They helped me clean up my room but now it's time for them to go
You shouldn't feel guilty for getting help, they want to help because they cherish you. You should take help when you need it, out of the goodness of their heart. They just want you to get better, so you shouldn't say no to such things.
Well, they should've asked.
When people go out of their way to help and show concern for you, you should appreciate it as a gift. Pushing them away is rude. It's not like they owed you their time and effort.
