Hello. I've noticed for a little while now that my overall thinking ability/mind, specifically things like focus, concentration, memory, a clear, consistent inner dialogue/train of thought etc. have, at least noticeably declined - at least compared to how they used to be, and definitely not how I would like.

I just feel like my mind is not necessarily 'foggy' (at least not the majority of the time), but just... lower, quality? Or functioning, maybe?

This is just one example, of like having trouble thinking of how to word and explain things. Like creating this post, or any post, I have to think a lot harder and use a lot more effort than I normally would, and what I'm thinking, and want to say, just doesn't really come naturally, and I have to really focus on it and think hard. Or just simply trying to find words to explain or say or write something.

I zone out a lot, and even when I'm not actually zoned out it still just commonly feels like I want to, or like my eyes/area around my eyes feels sort of 'heavy', like they just want to close, or my vision wants to unfocus, not and become blurry just into two images.

Reading is more difficult than it ever was before, or just processing/registering and intaking information in general. Like when reading, I have to really focus on and think about like every few words or so and process their meaning together.

When talking to people, anxiety or anything like that doesn't play a role, I just plain and simply can't think of anything to say 80% of the time. If my mind isn't just blank then any thoughts of what to say I might have are very superficial and small.

Like when you're tired, and/or like if you've eaten a whole lot of sugar, or like when you're distracted when there's a bunch of things going on around you, or like maybe a good example would be if you're driving really fast and looking out the side all the houses, trees, cars, people, etc. just objects in general are a 'blur' (not visually just mentally). I just feel like my overall mental and cognitive function, specific things aside, has declined, and I'm worried eventually it could get to a severe level where I can't function.

I can list a few things I'm sure that could be a cause/contributor to it all if that helps, like spending a lot of time on my phone and looking at the phone screen, a while ago being isolated all the time and having a very unhealthy lifestyle and intentionally doing things like focusing and fixating on to amplify emotions like anger, frustration, hate etc. and eating a lot of unhealthy food, along with drinking NyQuil to get high a lot of the time. Most of these were a while, like over a year ago, but I feel like they still could and might contribute to and/or cause the problems I have now.
