I'm working through my anxiety issues and am having CBT at the moment. This symptom has me a little bit beat though. It can very quickly come over me, usually if out shopping or if stood around talking to people. Even just at home actually! Anyway, my legs can get to the stage that they feel so weak that it feels like they will collapse from under me. I want to stop avoiding these situations but haven't quite got that belief that I won't faint/collapse and it's just anxiety etc. Can anyone relate to this?
