Cancer and being alone

So I'm in desperate need of some words of encouragement today.  My bf left sunday to arizona for surgery and radiation treatments for a month.  My LO's b-day is Monday so he won't be here for it  Things financially are extremely stressed and my bf lost his job due to needing the medical leave of absence and it being denied.  I am in school full-time getting my Bachelor degree in Nursing and work part-time in a clinic as an MA.  

 I wish I could say that its so hard to have him gone but what is really getting to me is that not much has changed.  Its given me a huge realization that he doesn't do anything to help with our DD! He also is never home when he's here so I am alone pretty much the same amount of time as well.  This is breaking my heart to realize that he's not really a part of my life on a regular basis We are high school sweethearts and have been together for 6 years.  When I think back to this time last year I remember being so happy and excited for our LO to be born.  I want our relationship to work out and we have always thought we'd get married but now I just have huge doubts.  Its hard enough to work out a relationship without the cancer in the picture.  I would never dream of leaving him while he's at treatment or anything like that I'm just having a hard time coping with everything and the realization about our relationship makes me so sad!   I am so stressed sometimes I feel like I'm never going to make it to the good times  Thanks everyone who bothered to read this and sorry its so long.
