> My colleagues said but nothing negative about my work.

I can read this either as "my colleagues said nothing but negative about my work" (what most others seem to be reading) or "but my colleagues said nothing negative about my work" - are we right in assuming the first?

> Edit:

Keep at it :)

I'm sorry for my bad English, it became worse, when I learned German last year :) My teammates are very kind and they are supportive. But I'm the only Front-end dev in my small team. I ask for help from people, who works in other teams. Almost everyone when I ask something, they help me/show me the right way. But I chosen to not ask often questions to hide my incompetency :) Here I understood that it was clearly a mistake. I have to be more transparent, especially now, at the beginning of my carrier.

No need to apologize - just keep in mind that some replies are written believing your colleagues are criticizing everything you do. Doesn't make the advice less useful, but it can affect the sentiment.
