I know how exhausting and frustrating and overwhelming it feels to have to begin again with another counselor, but I really think it would be so helpful for you if you can find someone who can see your more often.
Perhaps you can have your current counselor recommend someone who specializes in addiction, who has time to meet with you weekly, and who can receive and review the notes from your current counselor prior to your first appointment?
I hope you will consider advocating for your own health...you deserve it!!
