I really need some advice

I just found out horrible news from my mom...It makes me hurt so bad knowing what my grandpa is going through...He has to get his feet amputated, and is currently on oxygen...He is my hero in so many ways and hearing this has broken my heart...I know that even though I've only seen him a few times throughout my lifetime I will still be broken when he passes away...He has emphysema, diabetes, asthma, and so on, I wish my mom could go see him since he is her dad and all...She is getting the worst of it all and all she seems to do is cry anymore...I just needed to get it out...And I don't know how to make my mom feel better...And she can't see him because he lives in Germany....SO can anyone give me ideas on how to get money to buy a plane ticket? It will be deeply appreciated...
