Hi. Can you take a protein powder shake? That might help a little. If you get a quality one (no aspartame etc) then you can add it to water or to non-dairy milk (I like rice best). If you boost up your protein intake, that might help your body repair better.

You could even look into meal replacement shakes that will give you more complete nutrients. Maybe someone here can advise a good one. When I was at uni and not always able to eat properly I used to take a meal replacement drink to give my body a boost.
