I wish I could just feel a mood without it being read into

Ive felt really optomistic and excited about my personal life after some hardships. Yesterday I was excited, positive, and optimistic which gets treated with suspicion. Today I woke up at 5a.m. on a Sunday to get some hours in at my second job. My wife keeps asking me about a place on her foot which I have said the same thing "im not a dermatologists ". I was trying to nap so I admit I came off bitchy but it gets percieved as a mood swing. I can be tired without it meaning anything.
