I do not think it is wrong to miss being alone.
What is your reason for wanting to be alone right now?
Because I want to be by myself and I'm tired of having people around me 24/7
Not everyone is fit to be around so many people, you are just an introvert. It is okay to want to be alone and recharge, you don't need the bustle of activity all the time. Forcing yourself to interact will only let you get a break down.
You don't really get me, but I'm fine.
It is not bad to want to have some time alone at times. Every now and then people need some time to be in their own heads or just relax. Being around people all the time can be very draining for many.
