Seeking remedies for emotional reconnection

I feel like i'm operating on a low level mentally. Like i'm not using my mind as thoroughly as I should be. I use to be very intellectual and after some things happened do not feel very intelligent any more. Emotionally, I do not feel very stable. Socially, I barely make it by. I have problems reading and understanding. I feel like i'm in my own little world too much of the time and am trying so hard to be receptive to others. But I am not good at it, and it is obvious how hard I try sometimes. Idk if this will naturally heal itself out, or if there is something else going on here. I'd appreciate it if someone could shed some light.
