Minecraft obsessed! To many hours in one day

Hey so today and yesterday, I've been playing minecraft. Yes I know it's a very addictive game to play. Basically as I go college and I have now a 2 week brake. I Woke up today at about 10ish. Went on PS3 by 11 am this morning. Had breakfast, couple of drinks through out the day and that. Come of for dinner about 5-6ish. Then went back on and come of at 12:00am in the morning. I'm up now as I'm worried its early in the morning. I've got a headache from it, felt sick earlier. Feel a bit better I've had water, how can I cut down from going on this game? I went out after dinner for 15 mins to go to the shop, and when I came back straight back on the game. Same thing similar yesterday. Also it makes me very tired.

Why can't i see the full picture while my ps3 is connected to my tv via hdmi?

So when i plug in my ps3 via hdmi cable it works but when i'm playing games i can't see like the last inch of the screen on either sides nor top and bottom. Like in minecraft i can't see my bottom invintory and on skyrim i can't see my stats at the botton of the page. But with the regular hook up i can see everything fine. How do i fix it on hdmi settings?

Should I switch from ps3 switch to pc?

For the next generation of gaming I'm considering switching to pc. I have always used a playstation (3) for gaming and many games I played on my ps3 were exclusives or weren't available on pc. Most of the games I play are single player games like GTA, AC, infamous, RDR, uncharted, sleeping dogs,…
I don't play minecraft, FPS, MOBA's or MMORPG's. However I'm a little interested in strategy games like total war and stuff.
If I would build a pc, I would probably be using a controller most of the time and I don't know if that would always work well. Do you have to configure the controls yourself all the time or are they pre-set the same as they are on ps4 and xbone?
I also heard a lot of games get bad pc ports. So would it be worth it to build a pc?
Do a lot of people use a pc for the type of games I play?

Need a new Fantasy-styled RPG to play, any suggestions?

I want to play something new because I'm getting tired of playing Dragon Age and Skyrim. I play the medieval kind with swords, no guns (examples are: the elder scrolls and dragon age).

The games I've played (and own obviously) are Oblivion, Skyrim, Minecraft, Dante's Inferno, Devil May Cry series (1-5), Dragon's Dogma, Kingdom of Amalur: Reckonging, Deadpool, Dragon Age Origins (with DLC), Dragon Age 2, Nier, and Dark Kingdom.

I own a PlayStation 3 if that helps. I don't like any anime-styled games (always found them boring) and I don't like Final Fantasy.

Any suggestions?
