Do not listen to this stuff. Everything depends on you and the words are just only words. You know, we sometimes face the situations when it's essential to pull yourself together and go ahead without hesitation and panic ;-)

Be confident in yourself and you'll manage to do it. The main work was done, as far as I understand, and rewriting is not such a challenge. Good luck, buddy. I care about you :-)

It seems to me I could help (not writing instead of you but advice what to start with and how to solve the task). If it is not too late feel free to ask ;-)
