what is wrong with me and what can be done?

Ok so im getting really frustrated lately, i cant seem to concentrate and i keep having memory problems, i keep forgetting simple things like my keys or boiling the kettle for a cup of tea but then forgeting i put it on in the first place.I have started to notice alot lately that im a slow thinker and have trouble keeping up in conversation.I often forget what the person said and then i struggle to think of anything to say to keep the conversation going, this has turned me into a nervous person because i seem to avoid people when i see them.I dont avoid them out of ignorance, i want to talk to them but then i think the conversation will be awkward.My confidence just is not what it used to be, i rarely talk to anyone anymore and cant seem to express love or many emotions for that matter.Even a simple interview gets me on edge worrying that i will say the wrong thing or mess it up.I just dont feel in a good place at the moment.I dont want to be thick and i read to keep myself busy but sometimes its like things dont stick in my head.I sometimes have trouble getting up from bed and get alot of head rushes when i stand up.I find just normal thinking a hard thing to keep up, i get to easy distracted and to often go for the tv or music to sink into my own world.I shouldnt be doing that and every day i keep telling myself im going to get things done excercize every day and stick to a routine and get healthy.Well im doing the exercise but i just dont feel right in the head.Its like im in a permanent daze and cant seem to snap out of it or im permanently stoned if you get what i mean.
What do you think is the reason for this or is there any root cause?
can i improve my mentality or do you think im doomed for life?

also as a baby i did fall on my head(no joke) and had a fractured skull, do you think that could have anything to do with it?

THANKS in advance

If you live close to power lines I would move if I were you. I had this problem when i lived close to power lines and Im in my twenties. It's not been proved or correlated yet, but Im sure that it has something to do with it. Move! It will help.

personal experience.

man I feel your pain the same things are happening to me except I think yours is a bit more severe I don't know what is happening to us but my advice to you is to get a therapist. mine has really helped me out and understands me but most of all we are suffering from a broken heart.
