You're definitely not alone. I often feel the same exact way. I don't know if I feel it when I'm manic, or depressed, and really that part doesn't matter. I just know it's unbearable and it makes me treat those closest to me badly at times and that makes me sad. I try to basically just ignore it and treat my family in a way that I would want to be treated; it's not their fault. A symptom of BPD is being overstimulated and I believe this is what causes the irritation to noise, lights, crowds, exciting movies or video games, etc. It gets really bad for me when I take an exam at school. The pressure of an exam is a trigger in itself so all I can focus on are the amplified sounds of people sniffling or crinkling papers, coughing, clearing their throat. How do they expect me to concentrate in those conditions?? One thing that helped at work was finding a job where I worked independently. I worked for a company but I was able to go out and work on projects by myself. The only person I had to deal with was me lol! I know it's difficult but just try to put yourself in the other person's shoes. Good luck
