How do I Pray?

How do i pray for my food addiction? Do i pray for deliverance or do i pray for strength to bear? Is this the "thorn in the flesh" that i will always struggle with? Addiction, fear and anxiety keep me in prayer but i'm afraid i am not heeding the answer to those prayers. I fear that i may have to hit rock bottom before i truly learn my lesson. The thought scares me. Now i feel myself sinking deeper and deeper, my head is barely above the water and i am gasping for air. The harder i fight the more i drift. If i scream, will anyone hear me? I doubt i have the strength to try anyway. I want to rest, my mind and body are weary, but if i do rest i'll surely sink and be forgotten in the abyss. Could You tell me God, how do i pray?
