KSB. You are absolutely not alone with this and please know that is will shift. I woke terrified on holiday last Feb; shaking, panic, convinced I had diabetes for some reason, was ready to go down to reception and demand to be taken to hospital. I will have 2 or 3 weeks a month feeling pretty normal and able to do exercise, breathing etc - I think I've cracked it. Then every 8 weeks or so (now every month) I have a terrible week; feel old and scared and can't focus. I too have two young children and struggle to keep it together. The only tips I can give are eat little and often, try and get outside every day - even walk in the rain and distract yourself / keep busy. I tried HRT, CBT, self help NHS health anxiety course and am still on a low dose perindophril but to be honest nothing has worked when the ' bad' week comes - I think it is hormonal / chemical surges of who knows what. I have an un-opened pack of sertraline in my cupboard so interested to know how you get on with it.
