I feel mentally disconnected.

I’m probably extremely tired (just gone 6 am and haven’t slept yet) due to sleep pattern being a mess. I managed to get phone to charge so that is ok now. I don’t know what you call what my brain is currently doing. I feel like I’m numb and very far away. I’ve never felt that way before. I know that I feel burnt out but still somehow able to function… well, to a point. I was walking around my flat at a stupid hour feeling lost and zoned out. I probably have pushed myself too hard with exercise but I would rather do that productively rather than think of stuff that is bugging me. It’s not like walking can damage me but if I try to push it with others that could cause damage so this is my safest option.
