Please help!

This might be really weird but.. I can’t think. I have no thoughts, and I don’t know why. whenever people are talking to me, I find it difficult to understand half of the time. I can never say thoughts or opinions on things because I simply don’t have any. It’s really weird and bizarre. I also don’t remember a lot of things and I am really scared. Is something wrong with me? I don’t even know if any of this makes sense because I’m pulling all of these words out of my ass not even knowing if I’m saying anything right. Please, help. Please. I’ve been struggling with this for so long. I can’t even remember what I eat during the day or what I’ve done. Please someone help
