Welcome.
Living your life the way you choose doesn't mean you have to go off the deep end and choose drugs or get into dangerous situations. It is wonderful that you have spent your time caring for people. Many people have chosen jobs in the field of health care, fireman, police, etc. that are of service to others.
It sounds like you have definite goals associated with starting a new business. That, coupled with moving to your own place, should keep you very busy.
In time, perhaps your mom will see that you are pursuing worthwhile goals. Since you are the youngest, and the only baptised one of her children, she feels very protective of you-and yes, in a JW way. Hopefully she will feel more at ease soon as she sees that you are making wise decisions and advancing in your new business.
