My problems. I've spent tons of hours thinking over these things. I have problems expressing myself to the doctor. Any medfags got any advice on what doctor to see and what this may be?

>language skills deteriorating - Sometimes people think I type or speak like English is my second language, but in reality I am an American, californian, man who is 31.
>mix up words, when speaking/typing the wrong word comes out when I am trying to speak/write/type and I can't help it
>horrible at banter/unable to do it 90% of the time. it seems too mentally taxing for me, I just can't think of clever/smart/witty comments and keep up with other human beings verbally
>low verbal creativity. I am fine at answering/asking questions/stating facts i memorized but I have very few words to say when replying to someone's statement with another statement or when any type of creative speech is required of me
>can't flirt with a girl because i'm too stupid and slow verbally to be interesting for more than a few minutes tops. single my entire life
>spend tons of hours laying in bed staring at the wall while listening to music, have little to no motivation/drive/passion to do anything. i put on music simply cause it's less boring than staring at the wall in silence listening to my thoughts, i dont like music that much, it's okay i guess.
>will wander around the house doing nothing of substance, pacing from window to window
>no drive in life in general besides to take care of my lizards and cat, everything else i barely care about
>I dont care about having a career, fine living with my mom and dad till i die


I'm getting worse verbally as the years go by. And motivation wise. I used to at least want to get high, so i'd find drugs then chat to people online when high and read stuff all day. I don't even care about using drugs any more. I havent used hard drugs in 5.5 years now.
