I'm not going to help my friend in her time of need
What does she need help for and why are you not helping her?
I don't want to help anyone and especially friends
Whether you want to help your friend or not it is expected for you to step up and help her, especially in a time of need. If you aren't a reliable friend your friends might not want to be friends with you much longer.
I won't help her or anyone and it's just going to make me feel good.
You may run into some trouble in the future and you may find yourself lacking with people who are willing to help you and it will be the direct consequence of you not helping anyone when you can, so I hope you reflect on this and make sure that you lend a hand with your friend, as she really needs you right now.
