Zalan, Here in the state im in, you have to have your CNA in order for you be considered for a Pca or pct position at the hospitals here my city. You are right since you are the soul provider for your family. I think that is a good idea to stay certified just incase you were to lose your job in the future and you don't have to worry about becoming certified first before you can immediately apply for cna jobs. and also i think that for as long as you are working in the hospital i think by attending the inservices that the hospital provides to you, i think you should attend those because i think its a way for you stay certified i think. Wish you luck.
