what do i do?

hi, long time no type. long story short; i like this girl, she knows i like her but im not sure how she feels. it would be nice to talk to her about it and get some resolution on the whole subject. it has also been affecting me negativly, im having mood swings and such... anywho i hope i need to put this up here due to a crippling inability to talk about these things to actual people and this seems the best place to therefor aerate my problems.
