The different use of come and go in English compared with in Japanese can be confusing for students. Take a look at this link. I hope it helps.
We use the phrase ‘I don’t know if I’m coming or going!’ when we are very busy and flustered and cannot get things organised.

Hi! Thanks for telling ” how to use GO and COME “. Yeah, sometimes I’m confused about it. I read the website. I see, I got it, but I need to learn more about it. Anyway, I’ll come to your party tomorrow.
I’m glad you found it helpful, Yuria. Remember – ‘go’ anywhere, but ‘come’ to the the speaker or listener.
See you at the NELS party tomorrow!
