It is a good idea to begin with how we may help you, or end with that. It took me a while to figure out what you needed. Fill in the blank = directions I needed to see.
11. mañana
12. voz
13. dijo
14. veo
15. No te preocupes (don't worry)
16. cálmate
17. nada
18. Tengo
19. Yo te (I'm coming to you)
20. necesito
Without knowing your level (Spanish I, II, III, IV/V or the text you have used, I really don't know if this is what YOU would be required to do. In any event, what I gave you makes sense.
For next time: do NOT ask us to DO the work for you. DO what you can, tell us clearly what you'd like us to do. For this type of exercise, translate into English (if you must) to then make it easier to fill in the blank.
