Hi guys

I hope someone can help me answer this:
I had my Schengen Visa rejected and I sent an appeal about two months ago. It’s anyway too late because my travel plan was earlier this month. I applied at the Norwegian embassy in Bangkok. Now I want to make a new travel plan and start all over apply for visa. I ask the embassy if this is possible. They say I have to wait for decision for appeal or withdraw appeal before I can reapply. But they not give me any information about how to withdraw appeal, and not about how long time I have to wait after I withdraw it. If I understand correctly the processing time for my appeal is about five month. Two month already passed. If I withdraw my appeal now maybe it takes 5 new months to process my withdraw..? Someone know something about this?
My apologies if this topic is already discussed. I couldn’t find anything about it.
