Something you learn as you get older is that parents don't want to let you grow up. It's up to you to do what you feel is right so that you don't stay their kid forever, and finding ways to talk to your friends online is just one thing you can do on that path.
Hahaha oh wow. You cannot possibly be serious. If you are then I need to laugh harder. His mom cutting off his internet is in no way symbolic of a Freudian desire for him to crawl back into her womb. I'm sure your parents love you very much and you'll always be welcome at home, but I'm also sure that they would prefer it if you moved out into your own place instead of staying there and eating all of their food. Every parent would prefer that their kid leaves so that they can be sure that you can take care of yourself and so they can have sex without you awkwardly walking in on them getting it on. Yes they want to have sex, I know that thought disgusts you but they do. So do them a favor, man up and take care of yourself so they can get it on in that one place you liked to play as a kid
