Why are you losing, when you lose? Do you lose on time? Get mated? Botch your endgames? Figure out what's weak, then work on that.
The best general recommendation is tactics training, but depending on your specific weaknesses something else might be better.
Whatever you study, for blitz purposes you want to drill it so that you can do it *fast*. So if openings are an issue, for example, you want not only to know your openings but to know them without having to think about it.
Paradoxically, you might also want to train at slower time controls (10 minutes or more) because playing only blitz can leave you stuck, unable to improve because there's no time to reflect on what you're doing, so you'll tend to play just like last game.

Thanks..... that helps i think...
I play 10 min blitz..... i know my openings well.....my problem: when i try to play quickly and not be lower on time than my opponent, i am frequently blundering......and when i try to play slower, i lose on time, or get into time pressure and make bad moves....
I am literrally stuck...... i think i just need to improve my chess in general...

My peak is 1960, and I haven't really played for some time seriously so, currently it fell. Key to crossing might be, playing a faster format, but with a increment. In increment, you don't have to be on up clock all the time, and can win in technically winning positions, on increment. If you like 5+5, would be good, though I personally prefer 3+2.
I took down couple of 2000+ in form, and it won't be much hard for you.
Though i must say, guys up 2000 really test your opening preparation, I have guys, who played E4 and tested my Caro preparation upto 16 moves . So , you shall expect well prepared player. They will just know, right moves in opening, so to get slightly better middlegames, at first point, you need a rock solid repitore.
Also, just keep training, OTB. Training tend to push rating long term no, matter what format.

Thanks! Lets play sometime

You're currently 1800 blitz, so you already know the answer... you play games and review them, you study things you're weak at or don't know about yet (endgames, strategy, openings, whatever), and you solve puzzles.
I think one reason people get stuck is they refuse to study an area (like endgames, or learning a proper opening). Maybe because they think it's boring or too much work... but to improve you have to change the way you play, and you have to change the things you know about. If you're doing the same things over and over and not studying to learn new things then you're not going to improve.
