Hi Earthworm.
I agree, dont beat yourself up about not doing it this time round. I remember coming off them the first time, it wasnt pleasant! It took me about 6 months during which my anxiety increased and I also felt like I was back to square one but really I wasn't. I made sure I was mentally in a good place when I came off them, things were going well and that helped a lot with being able to cope with the panic attacks. I think you need to make sure your in a good place and feeling positive before you wthdraw, make sure you have the support you need.
You wouldn't think that you'd get a withdrawal from such a small dose but you defintely do! Once I'd withdrawn totally it took about a month for me to start feeling better. Wishing you good luck with this
