Have you spoken to your T about how you feel? Maybe when another space becomes available you would be able to go every week? I know you were getting on well with this T so maybe at least talk to them about how you feel before you quit? My T is about to go away for 8 weeks and I'm not looking forward to it one little bit but she is such a good T and helps me so much that I would rather wait for her to come back than quit.
