You may have bottled too soon, with too much priming sugar, or with too little head space.
Did you check final gravity over several days to be sure fermentation had stopped?
You can de-carbinate by chilling the bottles to 32F, then carefully, slowly un-capping the bottles, then re-capping with new, sanitized caps. This should let a bit of Co2 out saving the brew.
If it foams over when you de-cap, try just barely opening letting a bit of gas out slowly. You'll need to go slow and be patient.
