I made some bad decisions in my life that affected my three boys in negative ways - they are grown now and those issues, although not forgotten, are tempered with their maturity and graciousness. Fifteen can be a hard age - give your son as much support as he will allow at this time - but let him be the guide as to how much is dealt unless his actions become to serious to delay intervention - don't beat yourself up - that would just add to negative feelings - let your son see who you are as a whole, healthy adult - lifting you and your son up -
