Don't respond to that guy. Sorry to be so blunt about it but I feel strongly that you should not.

I know you don't think you are up or down and that maybe this isn't bipolar even but a character thing but it sure sounds to me like bipolar. When I am in a mess of states like that I often question what it really is if anything and I often think things happen all the time or I have always been like x or y but after the state (sometimes way after) I realize it was bipolar all the way.

So yeah I don't think you are okay right now. I think you need to get yourself safe. This sounds like a mixedish apathetic numb kind of depressed state. These are dangerous for me. Don't text that guy back. Don't go see him. I don't even think you should go anywhere right now.

Come back and tell us what is going on with you.
