Can't focus on the game

Recently I have not been able to focus adequately on my chess games. Thus, I'm loosing so many winning and equal position games. These stupid mistakes make me feel that I suck at chess which also causes some mental pressure since it is one of my favourite games. Do anybody have suggestions what should I do?
Cheers!
just take some time to relax. about 1-2 weeks off. then come back later and play 2-3 games the ones that you lost analyse where you made mistakes study them and get better, thats what helped me idk if it help u tho

++ Take time to think. Stop playing blitz and bulet and play 15|10 rapid instead.
Use all your time before move 30 and finish the game on increment.
"I'm loosing so many winning and equal position games" ++ Blunder check before you move.
