It's been a few days but I'm new to the board and wanted to respond to your call for help.
It sounds to me, like you are feeling overwhelmed and really would love to find a way to make it work, rather than lose your newest family member. You are a rare breed and I feel that you are probably the best caretaker that pig will ever know in his hopefully long life. It's so common for people to get a pig with the best intentions and then quickly dump them when they are bored, lose interest or whatever. It's refreshing to see someone who has the will, but just don't know where to turn.
Going on that assumption I want to reassure you that what you are experiencing is more likely the result of having either too small of a cage, and or a lonely guinea pig than anything else. Most of us don't spend that much time physically handling our piggies, as to be honest they would prefer to admire us all from a distance.. hehe.
There is a small chance that your pig may have some health issue that is causing this type of behavior. You also may be holding the pig for TOO long. One of my boys has to go pee about every 15 minutes. Somewhere around 15 minutes he's gotta go and start getting restless. At 20 he starts nibbling on fingers or going all whacky like they are scared and then by 30 they go absolutely crazy. If you don't give him a place to pee, he finally gives up warning me and lets a good HUGE pee and then relaxs and settles down. Usually that place is on you if you haven't given them any other option. It took me a couple months to figure out his ..bladder issue.
If I held either of them for up to an hour they definitely would be nibbling harder and harder trying to tell us to put them down to take a leak. Sometimes we misunderstand what's happening and feel stupid later on.
In addition,
nibbling is actually a sign of between with pigs. Does the "bite" actually mean a "taste"? While you may think he's biting you, he is more likely tasting you. Have you read the biting page at Cavy Spirit?
The reason your piggie seemed friendlier, is more likely that he was getting out of the cage and burning up his energy more often, rather than because you were handling him a lot. My boys tolerate me holding them but don't exactly wait for me at the door...unless of course I'm holding a cucumber or other treat! If you use a pet store cage, your cage is too small and what's happening is your piggie is full of energy, lonely and you are feeling his stress from it.
Have you considered how easy and inexpensive it is to build a larger cage the
"Cubes & Coroplast" way? When I first got my pig and started exploring the web about cavies, I was really excited to find
Guinea Pig Cages, Your Cavy At Home which is a site dedicated to teaching people an inexpensive and easy way to better their cavies life by simply assembling an inexpensive and larger cage. The site has hundreds if not thousands of pictures of people who have done it and many of them just children. The cost is also so cheap to do it that really no cavy owner has an excuse not to try it. Here is an example of just one of them

Then I found
Index of / and
CavyMadness,
Guinea Lynx :: A Medical and Care Guide for Your Guinea Pig and found out that they all need buddies. So I rounded up a local rescue and signed up a a buddy.
My pigs are in a nice large cage and they keep each other company. Being male, they have their OWN version of friendship as they do bicker a bit on occasion but mostly wherevery one is, the other is quick to follow. I spend about 15-30 minutes a day with them and an hour on the weekends while we clean the cage. I keep them in an area where we are constantly walking by them and talking to them. They have learned words like "Treat" "Cucumber" "Carrot" "Come-On". Words like "treat" can make them "WHEEEEEK" with excitement and the sound of plastic or even the sounds of me chewing a carrot will bring it on. Each time we walk by their habitat to go to the bathroom or get something from the kitchen they get some words from "dad and mom". We stop by and talk to them while they run to a hidey and peek out at us. I ask them if they want a "TREEET?" and if they wheek, they get one. Of course the treat is a piece of cucumber, carrot, celery or other veggie. They have learned what the word "carrot" means as well as a number of other words so they almost communicate with us. Right now, I honestly think they know what "poop" means, since I'm always talking to them about their poops, complaining about their poops, and cleaning their poops.
We have no children so these guys get a lot of love from us, just not all that much time. Guinea pigs do need human interaction, of course, to keep them tamer, but not to keep them happy by any means. As long as they have a buddy or two, a nice large cage, and a daily bit of time to run around in a playpen or other floor area they are quite content.
If you absolutely are dead set on not getting a second pig and/or alarger cage even after reading this:

then my suggestion is to take some time finding a rescue near you who can refer possible adopters to you, or posting an ad here at this site and on petfinder to see if you get someone you can trust to care as much about your pig as you do.
Personally, I think you would enjoy it far more than you know. I'm a 45 year old Cavy Slave and it's the LAST thing I thought I would end up calling myself.
