Too many of these threads these days, GY camping happens. It sucks, yes, but there is nothing you can do about it.
All you CAN do is learn to not take it anally and /afk out if the opposite team is GY camping. I've done it plenty of times. Surely not as many times as Pizza, but when alliance is literally at our GY making it impossible to get to the objective, I afk out and go for a smoke.
Just get off the game more, enjoy real life before you have to move out of your parent's house. Once you start looking at 19s the way most level-headed thinkers do, you will understand why things like this are so ****ing funny lol
Also INB4 LOCK
IN CASE TL; DR
Get over it, it happens. Try doing something else that doesn't involve killing brain cells.
