What has happened to me, is it a psychic disorder?!

I used to be the same way, but that was due to depression after people I knew died and my town literally burnt down in a natural disaster... (Black Saturday bushfires)
There's probably something that your feeling anxious about and havn't dealt with, or your finding the old routine boring. Perhaps find other activities you might enjoy, I found that the boredom was helped by me finding new activities, going to the gym, learning guitar, and also dealing with what was causing my anxiety.
If something is troubling you, go speak to a close friend about it, or even a councellor. Even though it's hard to open up to a councellor, it can be better speaking to them about things then to close friends.
I didn't mention my situation to make yours seem meaningless, I just wanted you to know that I've dealt with boredom in social situations... after the disaster I could only feel normal around people if I was stoned or drunk. Eventually I smoked every day, and when I wasn't smoking during school I'd drink copius amounts of energy drinks and take no doz to be productive. When my friends came over I'd get bored and sneak out and smoke... I felt so bad about this.
Eventually by dealing with the thoughts that were causing my anxiety I was able to deal with what was causing this, it really helped when I stopped smoking and drinking constantly as I was able to hang out with friends normally again.

I'm sure there's nothing to wrong with you, you just need to figure out why you're so bored and find something else that you enjoy doing. You'll likely be able to enjoy hanging out with your friends again. There's no need for you to feel guilty. Sorry if I went into too much detail about my own experience.
