Yes, on balance I have a happy life. I had a good childhood with a family who loved me and a steady early- mid teenage experience that was mostly uneventful in a good way.
My late teens to mid 20s were good in some ways - I met DH, got married, finished uni, got a good job etc, but they were very much overruled by crippling anxiety and mental health issues (which, in hindsight I am fairly certain may have been partly due to undiagnosed neurodivergence - it's still not diagnosed but that's because I haven't sought it...)
I was worried when I had ds that my mental health would plummet after being manageable for a few years but he's been a wonderful tonic and I would now say I am a person with anxiety that's mostly under control rather than the woman who was never not having a panic attack (genuinely).
I've much preferred my 30s to my 20s and think it's because I'm unapologetically me, and ok with that. I'm looking forward to my 40s when they come in a few years!
I'm still with DH and we are still very much in love - it's a comfortable, "you're my forever person and why would we ever even think about what if we broke up?" love.
D's is wonderful, albeit with his own needs (ADHD) which can be challenging, but he's amazing, funny, ridiculously clever and the child I was meant to have.
We have a lovely house and I'm senior in my career and finally love what I do.
