getting hard

Today I'm not sure what it is, it's just a hard day for me. My son was born on 11-4-16 at 27 weeks weighing 2lbs 8ozs he's been in the nicu 33 days and counting, and is now 32 weeks 2 days!!! He weighs 3lbs 14ozs now but I still just look at him and cry because he growing and doing great and now smiles when you talk to him and I'm at work 8-5 mon-fri and I feel like I'm missing everything already but I have to pay my bills!! What do I do?!? 😢😭😢😭l😢😭😢😭😢
