Do i have brain fog ?

I havent been able to think; and if I do its like .... mentally constipated(?) - for about 2 years now? I know I'm servely depressed (undiagnosed but in my defense I'm like 90% sure having constant like everyday thoughts/dreams/prayers of not being in this world anymore is not normal) and I cant even get help because I can barely formulate a question or something. I cant think and ngl I don't remember if I was supposed to say more. I might just be dumb though so apologies if Im wrong about the fog thing.
