Answer:
The strongest foundation of my life is God.
God is the reason I came into existence in the first place and since I acknowledged him in my life as an adult, I've discovered so many changes. Some things which I found difficult to do, or some addictions I found difficult to stop were easier to do, or stop.
I have a close relationship with my maker and it has been a wonderful relationship.
Personally, I feel nothing can shake or faze me, because whatever unfortunate situation I might be going through, someone else has gone through it, and succeeded.
