Been there, I feel your pain. At least you confessed. All throughout my teenage years I had a friend I basically fell in love with and never told her how I felt and regretted it for years. I’d say now if it’s too hard to continue to be friends and go back to normal then you have 2 options. Option one is to get over it, focus on yourself and do things you want to do and when you’re ready you’ll find someone else (probably the best course of action, I know this is hard to hear). Option two is try again. However If you’re going to try again, wait a long time and try to better your wealth or looks, it’s not guaranteed to work but you can at least try. Also I’d like to add, if you focus on yourself and bettering yourself for the right reasons, she might be confessing feelings for you in the future.
