I personally hate social events of any kind. I either want to be at home alone or hanging out with one of my few very close friends, just the 2 of us. Unless your paycheck depends on it, it's perfectly fine to skip the social events. Not everyone is super extroverted all the time. I have a very strained relationship with my parent so I can't exactly relate to you wanting to be with yours all the time...but if you (or they) feel that it's too much it might be good to find someone who is similar to you who you can spend time with sometimes. It's really not healthy to be with any one person 24/7 (even if it's your spouse). Or try spending some time alone and see how that goes.
