Like [@Undine] said, don't write if you don't enjoy it. Everybody has a hobby, and our interests certainly change with time. For all I know, in ten years time I might drop writing for bull riding or some shit like that. 

But if the problem is mostly that you feel as if you are being judged, don't worry about it. Nobody here is completely perfect (except maybe me but i don't know), just learn to take any critiques as an opportunity to improve yourself. Writing is like any other art, if you want to be good at it you need to seek chances to improve instead of seek evidence that you don't need improvement.
