'Think' is in simple present therefore we will use simple present tense only.

This is direct speech and we are talking about future so in this case we will use 'will be'.

Present continuous or present perfect will be used because we are referring to 'now'.
19. His friend did not help (not helped) me.
Simple past is used by adding 'did'.
