Being honest with my friend is something I should do, but it's difficult.
Is lying to them an option you are think about?
I'm really considering it. I just don't know what's going on in my head.
Wanting to be honest is a great thing, especially to a friend. You should always try your best to be honest even though it may hurt someone. It's better that they know.
It's hard to be honest all the time. I might get in trouble with my friend.
While their initial reaction might not be positive, it's typically a good thing to maintain honesty within a friendship. Have you considered that if you don't tell them now and they find out later than they might get even more upset?
