That's ok, I didn't think it would help you so much personally, but perhaps some others stumbling across it would see and realise there is a fairly clear and attainable route to getting Nardil prescribed via the NHS.
It is definitely worth considering Nardil, and also Pregabalin. (I would try pregabalin first because its efficacy would become known quite quickly). You might need to push some generalised anxiety type symptoms to get that prescribed, but it shouldn't be too much of a hard sell.
Good luck
