Ge out of apartment lease while on DEP????

When I go to MEPS, and lets say I get a ship date in about 3-4 months, will I be able to get out of my lease prior to that ship date? I have my own apartment and will need to move back to my parent's house since I will quit my civilian job so that I can spend time to focus on working out and preparing for RTC. I will have a part-time job at a pool, but will not be able to pay my rent for those months while I am getting ready for RTC. Will I be able to justify my need to get out of lease early? What will the process be like?
