This sounds really painful. I went through something similar with my T (different conflict, but also feeling abandoned), also leaving for about 2 weeks (and trying out another therapist in the meantime). I then realized I still wanted to work with my current T and emailed to ask if we could meet to discuss things. He told me I was brave for coming back and facing what had happened. I figured I'd see how I felt at that meeting, but he seemed to really listen and take in what I had to say. So I opted to start seeing him again. It seems like our relationship has improved considerably in the year and a half since then, that we understand and respect each other more (though we still have our share of conflicts, we work through them).

I hope something similar happens with you, that your relationship with your T gets stronger. The first session back will be difficult. But keep in mind that your T has chosen to keep working with you, no matter what you said to them. I hope you can work through things. Just remember that it may take a bit of time to fully trust them again. Sending good thoughts...
