Am sad for not being able to celebrate my birthday

Everyone has probably finished shopping for the Puja. But i cannot even start it yet as my disgusting exams are approaching. Every time my birthday also falls during the time of my exam. So disgusting! I could not even celebrate my Birthday for once except at the time when i was born. And i cannot celebrate it until i pass class 10 i think! When most of my friend's exams finishes mine starts. And i usually do not celebrate my birthday after the date passes.
