From what you have stated, there is nothing much you can do but to just return home. You can come back on a work visa but for that you need to have a job and a sponsor. The work visa will not allow you to continue your education.
You will surely be finding yourself in difficulties back home as you will feel like a foreigner in your own country. But then these are the disadvantages of staying away from ones homeland for so long at a stretch. Gradually, you will learn to live with the realities on the ground and you will eventually settle down. Many people and families have been through this situation earlier.
