Kacey, i can really feel how bad this is affecting you. I can feel your anger, hurt and sense of abandonment. I feel angry on your behalf, because what your therapist has done is so damaging, i believe he has done what he thinks is in your best interest and it sounds like he care for you a lot.

It may well be the case that dropping to once a week will help you to connect better with the outside world and that gradually you will cope better without him. This is maybe something that needs to happen and perhaps the 2 sessions a week are not helping you to be more self-reliant, however, what i cannot agree is in your best interests is to just drop you to 1 session per week 1) without making you part of the consultation process and decision making and 2) not making that transition as easy as possible by perhaps giving you a date 6 weeks ahead to prepare you for going to once per week sessions.

How can someone with trust and attachment issues be expected to cope with a sudden change and apparent withdrawal of the one source of stability and connection and support in their live???? Total bad move on your therapists part in my opinion. However, do you think you could maybe address this with him? Perhaps ask for a gradual introduction to the once per week session? And if you really can't cope after trying then perhaps the 2 per week will be reinstated with a view to reviewing the situation when you're more stable?
