What happens when you believe in kufr thoughts

Lately I have had a problem where I have severe waswas. I know that if you believe in these shirk/kufr thoughts then it takes you outside the fold of Islam. But the problem that I have is that I keep believing in these thoughts, and I don't know what to do about them. The thoughts come to me for the whole day, and even when I am praying. Then I have to break my salat because I believed in the shirk thoughts and I have to renew my shahada. Now I have to rush my salat before I can believe in another one of those those thoughts. I cant even sleep because of me believing them, and I get very frustrated about this and I get worried about this, because these are the last ten nights of ramadan. Am I still going to get punished for believing in these thoughts if I keep on believing them? I know that this is not just regular waswas, and that Allah might be angry with me for believing them. Is anyone else going through the same issue where they keep on believing these thoughts? Did any of you find a way to get rid of these thoughts. If so please let me know.
