You are a wonderful daughter, sister, aunt, and wife to think about and feel the pain of those that are part of your life. I know that you consider yourself more fortunate than other members of your family and I can feel your guilt & pain for if I were in your shoes I would feel much the same way. It comes from the love we have for those that we first shared life with. But God has given us a guideline when it comes to marriage of a man leaving his mother and a woman leaving her home and the two putting one another first as a new family. It is not you fault that your family members are going through such grief & pain. However as a family member you want to offer support in a way that will not take away from your immediate family....your husband.
Perhaps you can think of ways of being supportive that will help make you feel less guilt & pain. By making a point of emailing as often as possible and mailing little gifts and necessities that you can afford may be a start. Is it possible for anyone in your family to come for a visit to the states??? And if they cannot afford to do so would you be able to???? There are so many different things that you can do long distance to show your love & support for your family. Through the internet you can send pictures and letters to bring smiles to their faces.
I know that you feel guilty but think about how you would feel if your brother or sister were doing well...because you love them you would be happy for them. I am sure that your family feels happy for you as well. Where in Europe do they live???
I agree with Glamourgal....I would go to your church and see what support you can get from them and they may even suggest ways in which you can help/support your family and release the guilt you feel for not being able to do more. I know that often a church will adopt a family in need overseas and may be able to help your family out as well.
I hope you feel better and know that you can always come here for support. Your family is so lucky just having your love...that is a gift in itself. Please know that is what they need from you the most and it sounds like you have plenty of that to go around. Peace & blessings ~ Goody
