Sometimes I just can't help but feel so selfish.
Why do you feel selfish?
Because I have too many questions.
It is normal to feel selfish when you want too many answers to your questions. It can feel like you are demanding more and more things from people. You can try to find out the answers on your own so that you are not relying on other people.
I feel so selfish at the moment.
It is okay to feel selfish sometimes, but if you're able to understand that you're being selfish then you shouldn't do those things. I think you'll be able to figure this out, because I believe in you.
