Feeding problem

My 7month old baby doesn’t want to take bottle at all and doesn’t want to eat or try anything. I am so confused and so sad. When ever I try to feed him something he will just lock his lips and turn away. He will only breastfeed, which is tiring because he feed every hour or less through out day and night. Yes he had reflux but it seem to be gone 90%. I am supposed to go back to work next month and I just don’t know what to do. I also tried different bottles still.
