Hi there, thanks for replying.
The dread is often attached to future situations, i.e. the "what ifs". I've had some issues with dread in the past and it seemed to be triggered by feeling trapped - I was involved in two rather suffocating friendships (sounds trivial but I'd known them my whole life and felt constantly dominated and manipulated by them), this triggered the dread attacks to a point where I felt I could no longer cope and I removed them from my life. Although it was the right decision it took me 15 years of unhappiness, anxiety and dread to do this and therefore I really don't feel I can handle another situation like this again. Unfortunately a couple of people in my life are unknowingly triggering the anxiety, they are NOWHERE near as bad as the last two but certain behaviours remind me of them slightly (i.e. a little clingy, a little assertive etc), and this is causing massive amounts of overthinking the future, "What if I feel trapped again?", "What if I can't say no to them?". Even though I've been keeping them at arms length and trying to control the situation it really is causing a massive reaction in me. I'm too scared to tell them what I've been through and I don't really wish to remove them from my life (I also don't feel I can go through that experience again), I'd just like to stay calm, notice that I'm NOT trapped, that things are different now and practice being in control in friendships a little. But I feel the physical sensations have gone too far, am feeling pretty unwell if I'm honest. Hmm. Thanks so much for your speedy reply, it means a lot :-) I realise this may sound trivial but I have a feeling anyone with anxiety issues would understand. Thanks again.
