Welcome to our little corner of cyberspace.
I know how it is growing up singing and performing then having it stop cold... but in my case I also had a spouse at the time who enjoyed belittleing me any way she could... she crushed my self esteem when it came to my singing.... took me quite a while (and a good amount of liquid courage) to rebuild my confidance after the divorce.
If singing is your passion, don't ever let that fire go out... at worst, buy a cheap home unit and fire it up a couple times a week.. at best, get a sitter once a week and have a mommy daddy date night at your local karaoke spot!
