i dont recommend doing comfort over the phone or text messages... it ruins the bond you have together... comfort in this long of sessions needs to be done face to face so she can feel that emotional connection to you and not the phone she's holding in her hand...
she may feel that you're too clingy and scared to meet up thats why she's half flaking you... i'd probably give it a few days before messaging her... or even better... wait until she messages you

if she doesnt message you? move on

fuck her... its her loss
