I'm a glazier so I deal with this sorta thing on a daily basis. There ARE kits you can buy to DIY, although I've only ever used the professional grade stuff and I'm not sure how much different (if at all) the commercial stuff would be. There are a couple downfalls to the DIY method that come to mind... 1) by not applying enough resin into the chip, the glass isn't repaired and you've wasted money....2) by applying too much pressure, the chip turns into a crack and runs in any direction across your glass... 3) it isn't covered by any sort of warranty in the event that something does go wrong during the repair.
If I were in your position, I would have it looked at by a professional to identify whether it can be repaired or needs to be replaced. For now the best advice I can offer you is to make sure the chip is clean (the best method would be compressed air so you aren't putting any solvents or solutions in the glass) and then put a small piece of clear tape over the chip to try and help stop it from splitting any further. That wont last forever, of course, but it will buy you some time until you figure out what you want to do.
