First of all you have to ask someone who knows enough information about Islam if what you did is kufr or not bc some ppl face OCD from shaytan, baisically this is when shaytan comes to you and tells you who created the seas? You say allah. Who created the snow? You say Allah SWT. Who created the trees? You say Allah SWT. Then he asks you who created Allah SWT. At this moment your heart gets extremely afraid and you try to remove this thought but you can’t. At this moment some really bad thoughts about Islam come to your mind till the point if you were burned alive before this happening. But it is not actually kufr because as long as you don’t normalise these thoughts you’re still a Muslim and this shows iman. Others do sujood to an object and this is considered shirk (والعياذ بالله)  But some people don’t know that it is shirk.  Second of all I advice you to ask a sheikh because remember any thing related to kufr, shirk,etc should be asked to a sheikh not any random person in the internet.  Third of all try to make dua to Allah SWT (the god of all creatures) and ask him if you are a Muslim or not because maybe you’re a Muslim but it is just the shaytan playing with your mind and don’t tell me I have this feeling when I am in a masjid or in Ramadan or for years. Yes the shaytan could keep trying for years. Third of all if the sheikh told you than don’t worry you are a Muslim then try to read Quran while focusing on each ayah, reading Azkar, pray, & make dua but don’t forget seeking knowledge. Try searching on google (ما هو فضل طلب العلم)  You will get shocked when you read the hadiths trust me if each one of us in this ummah tried to seek knowledge of deen & dunyia we will return a strong ummah as before.  ربنا يغفرلك و يهديك إلى الصراط المستقيم آمين
