I was dx with PsA young. So I can say PsA has affected pretty much all my life decisions.
*I don't know if I would have been ready to settle down with my husband when we met in college, but I was already "old" emotionally from dealing with PsA, and it felt right. We are celebrating our 20th anniversary this year.
*I wouldn't have had kids so young (25 and 29.... both coincided with a 'good' period of PsA) except I knew I would get progressively worse. Now my husband and I are still young and our kids are both teens and pretty self sufficient. I look at my sister who had a child at 40, and a friend who had a child at 41, and they are really struggling energy-wise.
*I always planned to go back to work after my kids were born (I was halfway through my masters for library science when my 1st was born), but a combination of a special needs child and a PsA flare kept me home. Turns out being home was the very best thing for my children. My oldest needed homeschooling, my youngest is very sensitive and needs a lot of "mom time". My husband's job turned into a 10-12 hour a day job, so it helped him to come home to a family knowing everyone was being taken care of.
*my kids haven't been spoiled, they are very good about doing family chores and helping me A LOT. Plus, with my stories from growing up on a dairy farm, where I wasn't given much special treatment despite having pretty severe PsA, my kids know their household chores are EASY.
*I've really learned who my friends are, and though at times I've been down to only one or two friends, I always end up with a circle of 4-5 people I can tell anything too, who will do anything for me.
*I've become a great listener. I really enjoy listening to other people, and people REALLY like that. It's rare nowadays. My life can get boring if I'm having a period of time where my body won't function, so anything my friends say is FASCINATING.
*and like others said, I really cut to the chase about what is important and what is not. Playing games with my kids? Important. Keeping up with the Joneses? Not important.
