I feel like there is no hope I feel like I can’t get over this I can’t control these thoughts I don’t want them at all
does God know I don’t want them? & that I didn’t want to think them?
Hello Hopefully120, there is ALWAYS hope because of our loving Father's presence in our lives, though I realize that it can sometimes feel like there is not. So we do our best to rest in His great love for us
(a love so great that He sent His only begotten Son here to die on the Cross for us, to save us from our sins & the power of sin on this side of the grave, & to make sure that we would not have to live out eternity without Him, nor He without us
).
We can also stand on His great promises to us because He has shown us just how much He loves us, as well how trustworthy all of His words are .. cf
Romans 5:8-10.
And He promises us a better future in the nearness of time (not in the distant future) .. e.g.
Psalms 103; Lamentations 3:21-24, promises that are especially important to remember/trust/hold on tightly to in the midst of our most troubling times
(whenever we ~feel~ that the truth of His word/promises cannot be true, or that they, at least, cannot be true for us, that's when we must ~choose~ to trust them/trust in Him the most by making a conscious effort to remember to take Him at His word/believe Him .. rather than believing the lies that our feelings are telling us in the moment). Because we know that God and the truth of His word to us never changes
Lamentations 3
21 This I recall to my mind,
Therefore I have hope.
22 The LORD’S lovingkindnesses indeed never cease,
For His compassions never fail.
23 They are new every morning;
Great is Thy faithfulness 
24 “The LORD is my portion,” says my soul,
“Therefore I have hope in Him.”
I have a sense of the pain that you're feeling
(at least I do to a degree anyway), because when I left the very sinful life that I had been leading in my 20's behind to finally become a Christian at age 30, unfortunately, a lot of the mental baggage
(garbage) from my former, sinful life was still stuck in my brain, and it came along for the ride
This resulted in my having a HORRIBLE, PAINFUL and TIRING "thought-life" to deal with, terrible thoughts that just wouldn't stop coming at me many times. I would take them "
captive" in Jesus' name
(as we are commanded to do .. 2 Corinthians 10:5), and I would often have to do so over and over and over again
(they even invaded my dreams/nightmares sometimes back then
).
Since this is getting to be such a long post already
(sorry about that) let me tell you what worked for me to stop the 'onslaught'.
I tried all of the normal things first, like being as involved as I could be in prayer, Bible study, fellowship, witnessing, serving others, etc., as well trying my best to be walk in faithful accord with the things that passages like this one teach us ..
Philippians 4:6-9 (a passage that I believe @friend of has already mentioned to you above, in fact). I found that thanksgiving to God for EVERYTHING .. see
Romans 8:28, as well trying to always dwell on things that are excellent/praiseworthy to be particularly beneficial, just FYI.
Such things helped me, a lot actually, but the horrible thoughts, though reduced in intensity, kept coming, that is until I began to replace all of the stale, stinky mental garbage with something FAR better, ~memorized~ verses and passages from the Bible.
A pastor, Chuck Swindoll
(you will find a useful quote from him in my signature line below, BTW), told me that if I began to memorize verses/passages from God's word, that it would push all of the mental garbage to the back of my mind, and eventually out of it altogether. And you know what, that's exactly what happened
He also told me that while there would always be more room for additional verses and passages, and for things that are excellent and worthy of praise, as well, no room would be left for the foul garbage to return ~or~ for any new garbage to take its place. And once again, what Pastor Swindoll promised would happen is exactly what happened
(I am happy to report that nearly 30 years have passed since I first started memorizing Scripture and began ridding myself of the mental garbage & horrible thought-life 
).
I used/use the Navigator's
Topical Memory System to both help me memorize God's word, and to give me a very important systematic collection of verses and passages to memorize too. It's a proven system that the Navigators have been using to prepare/train their overseas missionaries with for nearly 100 years now
(and now it's available as an iPhone or Android app .. the Navigators had us using flash cards in the past).
I won't kid you, Scripture memory work is just that, work, especially at first, but I don't believe that there is another Christian spiritual discipline that yields more blessings, both immediate and long-term, and that to both ourselves and to others too
(whose paths the Lord brings us across).
And along with becoming a walking Bible, of sorts, you will begin to know Scripture and know the God of the Scriptures in an new and deeper way than you ever have before

Oh, and sinning becomes much more difficult to do, because every time that you are tempted to sin, the Holy Spirit brings 2-3 perfectly memorized verses to the very front of your mind to remind you why you shouldn't
I am VERY sorry to hear what you are going through, BTW
Praying for you.
God bless you! (
Numbers 6:24-26; Proverbs 3:5-6)
--David
p.s. - I'm not sure that memorizing Scripture will work for you like it did for me
(hopeful that it will though
), but if you'd like to try it, and you'd like some help getting started, just PM me and I will be happy to help in anyway that I can.
Psalm 119:9,11
How can a young man keep his way pure? By keeping it according to Thy word. Thy word I have 'treasured' in my heart, that I may not sin against Thee.
