I really don't know what too do! I am so stuck?

Yes I know weird title but I'll explain.

So I have been crushing on this girl for technically 3 years, But about 2 days ago I found out that another girl that I'm friends with (only for 2 days). Maybe has been crushing on me so I'm in a sandwiched place. Oh yeah and the girl who I am crushing on finally started warming up too me so I an completely stuck.
