I am trying to stop emailing my t for that exact reason. I obsess about whether (and when) she will reply. And then if she replies that she doesn't have time to respond to my concern, then i feel worthless and abandoned. It may not make logical sense, but that's how i feel. It feels terrible for me to reach out and be told that she doesn't have time, even if 90% of the time she responds. That 10% just crushes me. I wish i could accept that t is busy and can't always respond, but it triggers something deep inside me that already believes i am invisible and not important. Until i deal with that feeling, i think emailing and not getting a reply is only going to trigger it. So i am trying not to email my t.
