Prayer for Salvation & Faith

I'm stressed and depressed constantly about my living situation and life in general. My lease ended last month, but I'm on month to month until I find a place to move. My neighbors are noisy and difficult. My other stressors are my life not being in a place I thought I would be at this age. I feel like a failure and I keep asking God what's my purpose in life and I can't seem to get an answer. Please pray for me. I don’t want to feel defeated anymore. Jameel
