Question:

An isseu with my voice, cant sing as well i was able to before. plz help!?

so during the summer of 2006, i used to goto the karaoke alot. i enjoyed it, it was a hobby. i was able to sing very high and very well. (ima guy btw.) and after summer, ive been busy and wasnt able to sing much. slowly ive notice myself not being able to sing as high and as well as i was able to in summer. and about 2 weeks ago i was sick and my voice was out. im all better now and ive managed myself to hit the karaoke again and i wasnt able to get close to going high. a friend of mine told me to yell really loud and i would be able to sound squeaky and high. well i honestly though it wasnt much of a good idea so i didnt try untill i got other people opinion. is this a good idea? how else can i retrieve my voice back?
