I don't think there's a general absence of sympathy for OP, @simonsayss. She was mainly asking how to cope. She hated feedback that her daughter seems to be showing signs of emotional deprivation - that's understandable! No decent parent wants to think they may be failing their child in some important way.
There were, however, several respondents taking the position that OP shouldn't have to face the discomfort of her child's need for physical affection. They ridiculed suggestions that the girl's development could be seriously impaired, even when those suggesting it had suffered similar themselves.
They gave a strong impression that children who seek comfort in their mothers' arms are unreasonable, perhaps in need of treatment. Overall, they reinforced OP's desire to limit or even reduce the contact she gives her child.
It's really clear that OP finds it extra difficult. NT parents also get enraged by their kids' constant touching, mauling and inconvenient hugs; it's not as if you have to be autistic to understand that! OP made it clear that it happens a lot for her. There's no lack of sympathy for her.
And there's also a child whose emotional needs are not being met - for some years, apparently - and is inevitably acting out, trying as best she can to make up the 'hug deficit' with her family and friends. It's reaching a critical point for her, as she hasn't been able to stop the inappropriate behaviour at school. I think it's a compliment to OP's parenting that her DD still trusts her enough to seek hugs from her, but that won't last.
What's needed is a way forward. Few have been offered, though I did think there were a few good suggestions in amongst the snarling. OP can prioritise her own feelings, training her child to expect minimal physical affection. As a good parent, I think she realises the girl's already showing signs of harm and continued withdrawal will only exacerbate it. To help her daughter grow up sane, safe and balanced, she needs to find a way to make up the deficit.
I don't know what that is, but it won't come from yelling that autistic parents simply cannot stand it (and children shouldn't want it). Counselling might be an excellent idea, not to diagnose what's wrong with a child needing hugs, for god's sake, but to figure out what OP can manage to do to help her.
