Is It Worth Putting More Effort Into This Work

Hello, I have been working for about two years and a little for a large high-tech company. I started with great desire and enthusiasm, although at first it was terribly difficult for me, but the efforts I made did not go unnoticed. After the sixth month, the requirements for me increased, then the first more serious remarks about some things began, which may be completely normal with the increase in attempts to increase the requirements, but as if things were still under control. The real problems started in December last year, when I heard the line "You don't think" more and more often from the direct supervisor, he said that I work inefficiently and spend a lot of time on easy things, that I didn't know something simple, even though things are constantly changing. month, often every week. More and more often I have the feeling that I don't understand at all, which I work on and it's as if I'm hearing some things for the first time. I will say for myself that I am very emotional, although I do not show it. Also, I tend to make mistakes that are very serious for our work, even if at first glance they are a trifle, and the most worrying thing in this case is that I do not notice them, although I have checked my work several times, I have made all possible efforts to make things true, but ... alas they are not. It looks like I've done a lot of work and only I know how hard I've tried. I probably lack qualities. The nature of the work itself is complex. There are constantly changes that need to be monitored and reflected. Our database is under any criticism, I have the feeling that I am solving a puzzle until I get to what I need. As the pay is not high, it is not low, the company also offers a good social package. However, this does not compensate for all the stress I am subjected to. It costs me more and more effort to perform my official duties, and the result is not satisfactory. I have already made a decision, I just wonder if it makes sense to wait any longer, given that things are unlikely to change. And do you think it makes sense for me to continue as you read my story, or is it time to apply? Thanks! or is it time for me to apply? Thanks! or is it time for me to apply? Thanks!
