I’m stuck in a loosing streak
Losing streaks are normal. I once lost 10 in a row and bounced back and won 10 in row but that was my fault; I was drunk. So now I don’t drink and chess lol.
Space Podz made a good point. Sometimes you have to grind out your opponent and let him convert his win. I’ve had handful of games yesterday were I should of concerted the win; oh I needed those ELO points. I also started declining draws where I can convert an end game position.
Lastly, I prefer to look at win percentage of 50% or higher as a measuring stick.
Loosing streaks are normal. Just as the poster above said, and yeah, try not to resign too early because it's amazing what your opponent can miss. To rehash, they are normal. Even Grandmasters suffer the loosing streak phenomenon. Judit Polgar herself once said, "it's never fun loosing one game after another," but you should get up and try again.
just take a break
it works most of the time
I would suggest three things: 1) don't resign unless it is an absolutely hopeless case, 2) think through every move twice (at least) before making your move and don't be in a hurry, so as to avoid making ridiculous mistakes, and 3) play more chess, so you have more experience and more knowledge of what works.
It's very natural to lose several games in a row. It happens to me all the time, and will happen to everyone. If you lose a few games and feel like it's not your day, just take a break from live chess for the day and do some puzzles

Take a break. I was down more than a 100 points twice and after i took a break i immediately bounced back with a winning streak.
Take a break. I was down 100 points twice but i immediately bounced back and gained points to boot. One of those times was when i hit my all time winning streak of 15
