believing when confused

Being often sleep deprived, I am often quasi-depressed and often confused about God, questioning his existence and stuff. I wonder (now that I am sane again) what is the best thing to cling to in those moments? Straight-up trust in God and his amazingness might be one. Another more practical one might experience. We've had moments like these before, and we've always bounced back like a yo-yo. A third is that evidence for God is all around us. (see 'trusting the obvious') We are living right now and within Gods gifts. re is amazing. God is upholding it constantly (see the material section of 'TSM'). Our life and every breath we take is a gift. That is pretty good evidence for Gods existence I think.
