You have a wealth of resources available to you as a diamond member. Work your way through the lessons and do lots and lots of puzzles. And if you must play blitz (longer time controls are recommended for beginners), at least make sure to thoroughly analyze each game before starting another. The good news is that right now your skills are so low that almost anything you do will help you get better. Good luck!
I am bad at chess and need some help

Oh and if doing the puzzles is a little anxiety provoking due to time pressure, then try doing them unrated where you can take all the time in the world to figure them out. You can also set an upper limit for the puzzles that will give you a realistic chance at solving them and then gradually raise the limit as you get better. And if you have been working hard on your chess, reward yourself with a video; IM Danny Rensch is a great presenter. And again good luck!
"... for those that want to be as good as they can be, they'll have to work hard.
Play opponents who are better than you … Learn basic endgames. Create a simple opening repertoire (understanding the moves are far more important than memorizing them). Study tactics. And pick up tons of patterns. That’s the drumbeat of success. ..." - IM Jeremy Silman (December 27, 2018)

"... In order to maximize the benefits of [theory and practice], these two should be approached in a balanced manner. ... Play as many slow games (60 5 or preferably slower) as possible, ... The other side of improvement is theory. ... This can be reading books, taking lessons, watching videos, doing problems on software, etc. ..." - NM Dan Heisman (2002)

"... If it’s instruction, you look for an author that addresses players at your level (buying something that’s too advanced won’t help you at all). This means that a classic book that is revered by many people might not be useful for you. ..." - IM Jeremy Silman (2015)
