Ah yes, that's normal. I recall one day when I was feeling like hell, I walked into a shop and the shop assistant asked me 3 times in one visit "How are you today?". In my job, I never ask how people are, because they just might tell me (smiling). Note: I am a Pharmacy Assistant and most of my day is spent with sick people. On that day, I had been through a Chemo session, lost all my hair recently, and was scared. That's how I was that day.
What got me through those experiences was getting on here. Finding a community of people going through the same stuff. Warning my partner on good days, he may cop the brunt of my feelings, but don't take it personally.
All you are experiencing, every word you say, every emotion you have, it's normal. Take deep breaths and focus on the sound of the air travelling in and out of your nose. Perhaps you will do as I did, learn to Meditate and learn to shift your focus.
