Hello Ineedahug, I see this is your first post so welcome to PC!

I hope you find your time here to be of benefit. Once you have 5 approved posts, you will be able to enter the chat room and talk to fellow members. There is almost always someone online to chat with.
I would personally not express these feelings for her and continue to be a work friend, and nothing more. Keep working on these feelings in therapy and it should pass. Now you know the qualities you value in a partner though, because you see them in your friend. So if you ever try dating in the future, you'll know what to look for, which is awesome!
