Stumebeline, welcome to JWN. Take a deep breath and look for your option. You are young. You can make career in life with things you were denied as JW. Get education at local college to get marketable in job market. WT gave you some valuable skills that can be utilized in your college studies. You may enjoy doing presentation and lectures as we did in our KH. Realize you are free from man-made organization. Leaving WT does not equal leaving God. Situation with your mom can be only resolved by you. There is very little someone could do, except you need to make things workout. However, you need to look for your own future and secure well being for yourself to create family, friends, and happiness.
I do not recommend returning into WT. People who left and came back are ostricized as they are considered spiritually weak. The only exception is JW who have extensive family in KH. Read a lot, find out your options. Do not hesitate to reach for the government help to get grants for education or training. There is life outside KH, and often better than you will have in closed community. Good luck.
