I'm in love with my friend and I'm a bad person
Why are you in love with your friend and how is this a bad thing?
I am not sure how to hand this situation, it is making me nervous.
It is understandable to be nervous about in love with a friend. There's a lot of uncertainty but you should just try and do your best in the relationship.
Do you really think that? I care a lot about her, all I can think about is her.
Yes, and you should try to ask her out one time and see if she is also interested with you. If not, then you should respect that and set boundaries with her just being a friend. I still suggest that you care for her if she needs you and help her, as you don't want her to lose you as a friend.
