I am in general, yes. I truly believe that happiness depends more on what's going on internally rather than externally - so even when the proverbial shit hits the fan, I can still be happy inside. (And I usually am.)
At times but I'm very stressed. Our house is on the market and my husband already moved to where I'll go with the kids once our house sells. So during the week it's me alone, working FT with a 16 month old and a 3.5 yr old. For almost 5 months. I'm emotionally and physically drained.
