Hey Posey. A big, sympathetic ((((( hug ))))) for you.
Our son (two) is borderline HSC, with this manifesting itself in him being quite emotionally sensitive; taking things to heart, and really feeling upset about things others might be able to brush off.
We were out today at a zoo, and when it was time to go, took a land train from one end of the site back to the exit. Ds loved it - pulled by a tractor, too! The only problem was that when it was time to get off, he was distraught. I'd warned him we'd be getting off; I cuddled him and said I understood he felt sad and disappointed because he liked it so much; I explained about other people wanting a turn and that they'd feel sad if everyone stayed on and they couldn't have a go; I tried distracting him - lots. And he still balled, very loudly.
To make matters worse, he'd done a really big poo on the train, and so I needed to do a speedy nappy change under a tree before we left. Cue more hysterical screaming, despite firm but kindly Mum. All this went on with tons of glaring onlookers clearly making their silent judgments.
Horrible. I wanted the ground to swallow me up.
I was doing my absolute best, parenting well I thought, and I still had a big public tantrum on my hands which had to just kind of burn out.
So I do understand how you feel about the HSC dimension, the public wobblies (especially in front of "friends" - I too now have a friend-to-avoid for this reason ... although she is pregnant again and I'm half-hoping it'll be a challenging one!), and the judgment (which I too find hard not to take personally). It too has changed my perspective, and (I hope) reduced my own judgmentalism. However a child's behaviour/parent's parenting looks, it's so often not the full story.
I love other posters' responses on here. And the HSC site/book will really help you see the positives. For example, ds's intense emotions mean he is also really empathic and concerned for others' feelings, and he's only just two. Yay! [proud mummy emoticon]
