I am having this problem right now. My therapist has always been good about responding to emails by the end of the day. Every day. There was a point at which I emailed him every day when things were rough, and he always responded by the end of the day, if only to let me know he got the message. Now, in the past couple of weeks, I've sent him like one email a week, and he has taken a long time respond. Right now I'm on my third day of no response from him and it's been extremely tough. I feel so triggered. I know I need to talk to him about this tomorrow, but it sucks. I just want to feel better--I don't want to be so desperately needing this person all of the time. Sometimes I don't know if therapy is helping or just making things worse, but I know I'm terrified to quit. Sorry to hear you're struggling with feelings like this too.
