Increased anxiety have agoraphobia and bpd. can't sleep or eat. have had panic attacks and a blackout with confusion for 30 mins, what is it ?

Complex issues: It sounds like you've been dealing with multiple issues at the same time. Have you also been drinking alcohol? This is a common cause of blackouts and confusion. Are you on any medications? Have you been receiving psychiatric or psychological treatments? I suggest starting with your primary care doctor to evaluate the confusion, and ongoing care with psychiatrists ; psychologists. Be well.
