Anxiety strikes again !

Just feel like ive been hit by a train ,anxiety levels through the roof,and i can bearly get off settee,just want to sleep.No apparent reason for it,very disheartening.A friend of mine text me and said 'Well we just have to get on with life' and i felt angry and text back saying 'well i cant get on with life cos its so incapacitating sometimes',people dont understand,im gratefull i found this site where so many good people that do understand.
