What to should I say in this the following situation?

I just decided to quitting quit my job. My best favourite co-worker said "I am sorry that you have to go."

What How should I respond?

Please note my changes above. We do not start a question with "What to" or "How to".

There are hundreds of things you could say in response. It depends whether you want to elaborate on your reasons for leaving. The simplest answer is something like "Thanks. I'll miss you".
