Yes, I do believe in God.
I have SA, and Depression for many years, and without knowing God, reading the Bible, and having other fellow Christians in my life to lean on for support, I would feel more lost than without Him in my life.
Sometimes, we are given issues to learn how to turn to Him and lean on Him to let Him help us.
Within the last year and a half I have had my SA tested to beyond the max. and as I look back at the worst days I went through, I don't see myself making it through that time. Rather I see Him carrying me through it.
I use several Bible passages and praise and worship songs to help me through my daily life, and especially when I am having really rough patches.
