You had expectations for the text. When your expectations aren't fulfilled it drives you further down.
Rather than trying to control your feelings, feel them for a while and then let them go. My IC gave me a really short meditation technique for this that works really well.

Waiting for an answer on here can feel like a lifetime but most of the time answer does come and unless there is a rush you should wait for the answer because it might let you move past what your feeling as well as getting good advice.
Be careful your step closer to detachment from her isn't just based on her ignoring (assuming she got the text anyway) you. Contacting her and not getting anything back will make you feel like there is less chance of R and so your further away from W. It will also "possibly" make you even more desperate when she does maybe contact you.
