Wow I can really relate to some of this. On one hand, I think it's really good that you're content with yourself; but I'm sure your friends and family still want to have you around often and interact with you. I know that for me, I've been trying to find a balance between giving myself the rest and space that I need, and spending time with my loved ones in ways that are best accommodated for me (for example, having coffee together instead of spending a whole day away from the house where I could get sensory overload). I hope everything works out for you :)

I get what you mean for years I was so sociable people oriented loved hanging around my friends but this past year I just withdrew and I've become this introverted introspected version of myself I used to be very withdrawn from the world in my preteen years and I have to say I've learned alot more about my inner workings as well
