There are so many ways to 'get a new lease on life". And as allmymarbles stated, you need to open up a little and tell us your circumstances before we can be of any help. We hope you do this, and not just let it go at this. You don't need to be alone!! God Bless You!!
Why are you treated like a child? Are you behaving like a child, or have those around you type-cast you? As for getting a new lease on life, please tell us more about yourself and what bothers you so that we can try to be helpful?
