I hope you can find a family member or close friend to really talk about. It sounds like you need help from someone close to you. If you lost your job, is there not disability or similar you can apply for?

Have your meds helped you in the past? It sounds like you need them adjusted. I'd write down my feelings that I am feeling right now, as by the time you see your p-doc you be ok, and not be able to really express your feelings. That's what I find, and then we battle to adjust my meds like we are supposed to.
How about going on holiday somewhere and allowing your mind to clear up; surrounding yourself with positive influences.

I'm not sure if it's typical of BP, but I can really empathises with being overly sensitive. I battle with this too. I usually land up in an arguement with my bf, and end up having to apologise. Try and slow down your reactions, and give yourself time to process the response you wish to give.
