If you feel that the company is so very good and you would love join back, what is holding you from discussing the same with the management? It is better you talk to the management and see if they are interested in taking you back either from where you left off or as a fresh employee. As you have worked for less than a year it should not matter much if you want to stay put in this organization. Do not try to ask for relieving letter or final settlement at this stage, you will spoil your chances of getting back into the company.
Also are you sure you can convince the management that you couldn't even communicate to them during your sickness period? Better keep all the records when you talk to them. Good luck.
Thanks and Regards
