Good luck with your appointments. I think it's ok. When I started therapy a few years ago I started doing cbt online through the nhs. I knew our time was coming to an end and I was really struggling as there was this big issue we hadn't dealt and I just kept crying and all I wanted was to keep speaking to her but we had done 15 sessions and that was more than the maximum with so just before we finished I found a private t as I couldn't cope with the thought of another t finishing before I was ready. I didn't tell cbt what I was doing as at the final session she said I could refer myself back to her but would have to wait 3 months I think. I carried on seeing private t but all I kept thinking about was I needed to tell cbt t the other stuff. I waited the 3 months and although I felt attached to new t I was still obsessed and crying over old t. I referred myself back and managed to get her again and completed 18 cbt sessions with her. Neither t knew I was seeing the other, new t knew about cbt but I told her it finished a few weeks before I started seeing her. I'm really glad I did it. I felt closure after I finished with cbt t which I never felt the first time. She did say I could refer myself back to her to do sessions on my low self esteem. I'm tempted as I only see new t fortnightly as that's all I can afford and I miss the weekly sessions but haven't made my mind up. It's been 5 months since I've done cbt so can phone up anytime to restart and every so often I will think about her but I'm not obsessed like last time so I don't know what I'm gonna do but if you think it will help you especially as they follow different models I would go for it
