I wan to resign from my state govt job

I have been working as forest guard in M.P for 11 months till may 2017. i wanted to reisgn from my job but its really stressing me out. I talk to my superior about the resignation. in june 2017 i took sick leave for 3 days & send email for leave application and called my superior to ask for leave. I got well but still I didn't go to duty & lied that my condition became worse. Since then I didn't go to the duty and switched off my phone.In July I received notice from my H.Q. through Post asking me to be present on duty within next 2 days otherwise strict action will be taken against me. So I emailed resignation letter very next day. I mention my poor health as ground for resigning and mention that I cannot come on duty because I am still not well & will take more time to recover myself. Till today I didn't received any other notice. I Don't know if they accepted my resignation by just email. Can I give other govt exams without mentioning about this state govt job in the application. Will this cause any problems for me in future if I want to go for other govt jobs. please help me what should I do.
