Jacob,
I've been there and done that and am now trying to burn the t-shirt.
I am a sex addict that is forgiven. There have been many battles in the war against my addiction. Some have not gone well. Suicide is the easy way out. I've prayed MANY times for God to take me out. He even prevented me from doing it myself. Listen to me, GOD LOVES YOU no matter what you have done or when the last time was you did it! All he wants from you is to be TRULY repentant. He will handle the rest.
You said 2 scriptures come to mind. BE VERY CAREFUL of what you allow to stay on your mind. Those scriptures you quoted are good, but remember that satan quoted scripture to Jesus. My point is, there may be better scriptures on which you should focus. Check these out (All NIV):
Psalms 18:16-19 Remember you are no surprise to Him
Psalms 23:4 His rod and staff correct and guide you
Psalms 25:7
Psalm 31:24
Psalm 32:1-2
Psalm 51:10 Pray and ask for this
Psalm 51:17 This is a promise that He will forgive you
2 Cor 12:9
Gal 5:17 This is the conflict within you
Eph 1:17
Phil 1:6 He WILL be with you through all of this
Phil 3:13 Repeat this out loud to yourself
Phil 4:13 I have spent hours saying this to myself. It brought me through the darkest days
No matter what you think of yourself, God wants to forgive you. And He will continue to forgive, it's not a one time thing. But you must ask for it and be truthful with yourself and Him. I was an addict for 40 years, I KNOW He wants to forgive you!!!!!
I'm in NC but God is everywhere. Sometimes He wants to be all we have so we can learn more about Him. It's tough when you're down and want someone to talk to. If you can, get to a private place and talk out loud to Him. Not the praying kind of talk, but just like you where talking to the partner you want to have. There is nothing you can say that will shock Him, and there is no one He will gossip to. The huge weight of guilt and condemnation you carry is NOT from God. God DOES NOT CARE what you have done! He wants to forgive and take the guilt from you!. Dude, you CAN BE FREE!!!!!!!!!!
After you sincerely ask to be forgiven, don't worry about how you feel, just keep repeating appropriate scriptures to yourself. You may not know the difference between satan's voice and God's voice. That's OK, most people don't. Believe the scriptures you read, not what you are thinking or feeling. After all, your mind was where your problem began. It must be renewed with good stuff.
I'm praying for you
