i'm sure it will. i totally get what you mean by these, albeit i imagine we experience it in different regards. for me, when i write i feel as though knowing i have improved over the years make me hold myself to a higher standard, and so i'm constantly striving for a goal i can't reach which deters me from writing at all and causes a huge writer's block for me. i'm confident that your want to finish something again will push you through the anxiety and eventually the anxiety will go away though. <3
