He did try to reassure you, but you shut down and shut out his message because you had already decided to interpret what he was saying in the most negative light. You have to stop picking and choosing what to listen to when your T talks to you. You latch onto information that you decide to interpret as negative/abandonment, while completely ignoring the whole message about this will be a long process, nothing immediate. In other words, he's going to work with you until you can eventually stand on your own two feet down the road. Don't jump from A to Z on this. Your T didn't jump from A to Z and in fact explained that to you, but you are choosing to even look at the reassurance that you heard him say (you are the one who reported it to us).

Down the road, probably WAY down the road, being able to stand independently and not have to see him twice a week or even once a week will be a triumph and achievement for you. And trust me, it will really feel like an accomplishment, not a loss, not an abandonment. You'll be proud of yourself when that day comes. THAT is the message of reassurance your T was giving you.
