Well, parents are overprotective these days about the risks that are involved using the internet. Yesterday, my mum showed me an article these men who met up through the internet because they have his thing for cannibalism, as well as getting eaten themselves, and one ended up getting eaten altogether (I won't go into the article too much as it's very sick). Proof positive that mums are usually compulsive worriers. Personally, your mum needs to relax. She should know you're strong enough to look after yourself. That said, if you are overdoing chats, then maybe you should make a compromise with her.
Oh, and another suggestion. Try bashing and smaashing a useless, inanimate object with a hammer or something. You are a bit peeved Lime, so let off some steam!
