@Rose76 - It sounds as though you already know what will or won't work in regard to a professional helping you, which is a good starting point to go into any kind of therapy with. Even though the Psychologist said this was short-term, it might be worth clarifying with him if that is flexible, ie if you needed more help/more time, would that be possible?

I doubt very much that he would terminate seeing you because you weren't trying hard enough, lack of motivation is partly what has driven you to seek help in the first place; he wouldn't be doing his part if he gave up at the first hurdle or showed impatience at lack of progress...
Maybe tell him what you have written here, explain that your improved state of mind just collapsed. Maybe you already know why this is, but if not, explore that with him.

With regards to the counsellors, it may be that they're treading lightly until they get to know you better, however, receiving unconditional positive regard is all very well, but fairly useless without a bit of counter-challenging. If you decide to stick with either of them, perhaps this is something you could raise, that you need more than empty platitudes and affirmations.

Perhaps stick with just the Psychologist for the time being, keep the counselling in reserve for later if you still feel in need of support...?

Just a few things that came to mind as I was reading your post.
