please tell me it gets better!

today was my first day back at work. my 3.5 month old was home with my husband and before I left her I nursed her. we have tried her on the bottle a few times before but she has refused. this is the longest we have spent apart and I didn't even work a full day, she has just been crying all the time and refusing the bottle. I figured if she was hungry enough she would eat and I know it's only day one but how can we get through this? perseverance and extra quality time when I am at home? words of wisdom greatly appreciated.
