Over reacting?

So some one posted a post asking about advice about should she try fir a baby at 17 I give my opinion and was targeted by about 12 people telling me I can’t have an opinion if I haven’t got a child! This made me very upset I don’t know if I’m being sensitive or 😕I commented back I would have a child of life wasn’t cruel she commented back “lol” as a person who can’t have children And that has suffered 2 mc this actually hurt me dk if I’m being sensitive 😕
