Hey,

You mentioned telling your mom you are open to other forms of affection. Did you give her ideas on what the ways you'd like to give and receive affection are? It might help her to have a solid idea of what she can do.

When she goes to hug you, I would move away and say "I do not want to be hugged," and repeat that as many times as she tries to hug you. If she says you are being disrespectful you can say "I understand this is how you show affection, but I do not want to be touched."

When she comments on your weight, you can say "this conversation is over." You can either repeat that or even walk away when she continues to comment on it. She'll probably consider walking away to be disrespectful but she's giving you the same disrespect by commenting on your weight after you tell her you don't want her to. Maybe after a few times of you walking away she'll start to get the hint that this isn't a conversation you want to have.

Also, for your own reminders, you can be healthy at any weight. As long as you are taking care of your body and your doctor says you are healthy, that's all that matters.

You're not posting too much either. There's no limit.
