Answer 1

genki ja nai sounds ok to me but I'm not sure, not a native speaker

watashiwa asagohan o tabemasu

asagohan=breakfast

hirogohan=lunch

bangohan=dinner

just substitute those in

watashi no yume ni ikitai

(i want to live in my dream.  dream is close enough to fantasy in japanese I think)

kurushimi and kanashimi are 'pain' and sadness' don't know how to say I'm trapped in though...
