Everybody's struggles are different.  It's easy for someone who's not going through it to say, "oh well, just hang in there," but I think it's okay to be hurt and crushed and cry and be angry and frustrated - that's all part of it.  I think people stopping you from doing that is not helpful at all.  It's important to rally around people that love you, because you tend to isolate yourself from people so as not to worry them.  But, the people that love you worry anyway so you may as well rally yourself around them and let them be there for you.  Cause there's a huge chance that they'll need you sometimes too.
