I think some people resort to making such statements because they don't know what else to say. Sometimes it's easier than giving real help or advise. Sometimes they can not put themselves in your shoes because they are well and don't undertand how weak, helpless and depressed someone can be. Sometimes you just can't "snap out of it" or "pull yourself up by your bootstraps".
I think everyone always thinks...will this cure the problem? A one time donation to help someone normally is not enough. Most people are in a cycle of distress that they can't get away from. Add illness to the mix and it just compounds the problem.
If you don't mind I would like to pray for God to give you an empowering spirit for living life. May your eyes only see the joys of living for Him and feel the power of His Spirit lifting you up and reminding you that He is with you always. amen
