Help with Improving reactive Play, and single move Sightedness.

I've been playing a couple years now, and I know that overall I have improved my play, but even though I'm not a complete beginner, I still get hung up on a seemingly easy concept that for me is extremely difficult. I make mistakes, when I start playing reactively and can't see several moves ahead. I do try to calculate, but somewhere in the middle of games is where it all seems to fall apart, and my opponent starts putting pressure on piece after piece after piece until I either blunder, or go down in material because I calculated incorrectly. is there any tips, i.e. certain drills, books, lessons, that can help me with my single move Sightedness, and maybe help me with counter play? thanks.

It looks like you only played two games in the last two years.

Your board vision will undoubtedly improve if you play a little more frequently.

I've played a bunch on lichess, and chess tempo.. I had forgotten about this account on chess.com.

And when I restarted playing on this acct, my plan is to solely play 10min or more. I scored 2 wins off the bat, but I don't expect to keep that up for long.

Sadly I'm clueless about what you meant.

Well, come back when you start losing regularly again so that you have something to look at.

Okay, so until I start losing, I'm unable to get tips about my initial question? Wow okay.. believe me when I say, I rack up plenty of losses on lichess and chess tempo. I didn't realize that asking a simple question would be this difficult on here. Sorry I asked,

What the hell? What sort of response is that from a MODERATOR?

You guys need to sort it out. I was going to reply and contribute to the discussion but how can I after such a cynical comment from a MODERATOR. A moderator that probably doesn't even know what cynical means.

Weird energy here, the OP asked a question in earnest and deserve an answer.
I too have experienced the frustration of blundering when I get tunnel vision on a particular plan I'm trying or just don't notice that an attack was revealed. I think it's extremely common in people who come to chess a bit later, and probably kind of hard to understand for people who grew up playing a lot of chess and have a sort of internalised sense of vision which makes these kind of attacks seem unmissable and obvious and very natural.
So I try to work on it and the most obvious thing I do is just slow down. At the moment I like to play 15+10 games, and very often I'll use more time than my opponent. But just taking an extra 5-10 seconds with each move to think 'am I hanging anything?' has worked wonders to prevent the worst blunders, and taking the moment to look at the opponent's move and figure out what the threat is is preventing so many blunders.
As I get more experience with the sort of blunders I make, I try to take special effort to look for them. I know that I miss diagonals more than I miss attacks on files or ranks for example. I used to miss a lot of knight attacks, but after working on it I see them easier now. As well as playing games on various sites I practice against bots just to get more play in with less pressure.

I don't know if this response amounts to anything more than 'just work on the things you're bad at' but ... kinda that IS the advice, you know why you are losing, so that's something you can pay more attention to in games right? And the way to pay attention to it is to slow down. Give yourself time to think.

I've won 15+10 games where I've been down to 8 or 9 minutes and my opponent was still on like 14, and me using all that extra time, it turns out was much better than them rushing into moves that eventually led to blunders. Sure, sometimes I've got into time trouble too by getting too low on time to think about my moves, but not as often as I've done well due to taking the time to consider. Speed can come later.

Before finalizing your move, ask yourself: “What does my opponent do next?” This habit helps catch oversights.
