What server? Lol!
In my experience parents go through 3 phases: Denial, mourning, and acceptance.
Denial is difficult to deal with... I had to deal with it for over 4 years with my parents. Right now, you're always be your mom's little boy. This is a phase and you'll grow out of it, those video games are making you feel this way, any other stupid, ridiculous thing they can come up with... This does mean, that your parents love you. It wasn't until I made real strides in getting my transition going that my parents moved on to the mourning stage.
One thing a lot of people I've known don't realize is as much of a journey your decision is, your parents have a similar one to make. You may have spent years wrestling with your feelings, but your parents are just beginning it. Things take time and there is quite a bit of mourning that takes place. Undoubtedly some of your parents hopes and dreams for you are gone and accepting a new person (you basically are a new person) while the wounds of losing a loved one is still fresh is very difficult.
Finally there is acceptance. Your parents still miss what they have lost, but are accepting a new person into their life. This may be very similar to the person that they have lost, but is inherently different. Be warned, mourning and acceptance can take place at the same time...
With the gaming thing... its definitely possible to be addicted to video games. Its an escape... a fun one, but an escape. Sometimes that escape becomes more real than reality and there can be issues. Again... speaking from personal experience.
