Hello,
I believe you have posted in the right place. Your concerns can be deemed "mental" rather than "spiritual".
Don't worry too much about it, you are not the only one. I understand your concern of those Scriptures and with others since I struggle with things like that everyday. I tend to try to make light of situations but sometimes, especially when something is serious, my mouth feels as if it's going to laugh or smile and it makes me anxious.
I don't believe God is watching our every move AND waiting to see if we sin, but remember that God has reconciled Himself with us through our Lord Jesus Christ.
that God was reconciling the world to himself in Christ, not counting peoples sins against them. And he has committed to us the message of reconciliation.
- 2 Conrinthians 5:18
If you believe that Jesus is the only way to the Father and believe in Him and what He has done then God will never leave you and will never forsake you.
The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full.
- John 10:10
That is eternal life, kept in the might hand of the Father through Christ which no one and nothing will ever be able to separate.
It's also good that you hunger for righteousness remember as it was said:
Blessed are those who hunger and thirst for righteousness, for they will be filled.
- Matthew 5:6
For through the Spirit we eagerly await by faith the righteousness for which we hope.
- Galatians 5:5
I am definitely with you - that I don't want to sin, keep steadfast to the hope which we have in Him.

I understand the nature of OCD. Even after hearing about the things above, about how much God deeply cares about us, there may be those lingering doubts that still lurk somewhere in our brain. I would recommend seeing a doctor or a Christian Counselor to confirm if you do have OCD (Scrupulosity as its religious side is called) and getting help from them could benefit you.
Finally I want to share something that happened to me this morning (sorry for the long post so far); I woke up feeling depressed, I felt completely unworthy and inadequate. All my failures, my current self and my OCD just made me feel like I'm wasting away. I then prayed and immediately I remembered this Scripture:
But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me.
- 2 Corinthians 12:9
and it renewed my strength.
Don't give up! Praying for you,
Rustom
