I'd like to thank you all for your kind comments and suggestions, it always helps to hear you're not alone
I saw a counsellor for several weeks, but found it unhelpful. I've also been seeing a hypnotherapist and have been to approximately 6-7 sessions. This I find more useful but still only takes the edge off. This week I was referred to another counsellor via my Doctor who has suggested CBT, which should start fairly soon so fingers crossed.
I use beta blockers to stave off the worst of the panic attacks and started using St Johns Wort about two weeks ago. I think its helping but it is supposed to take a while to build up its full effect. I know a lot of people find prescription meds useful but im against using them myself as I had a bad reaction to benzo's a few years ago when I first started having panic attacks and sleep problems.
Thanks again for the comments, and I hope I can be helpful to you guys in the future.
