I have no idea what the soldier's angel thing says(I'm already a soldier's angel

) but I doubt that the website intent is to stress you out. I think it is for people that can make room in their busy lives to drop the soldier a card or letter or email or package on a semi regular basis. I don't even send my husband something every week.
What I recommend you doing is buying several of those 50 cent or dollar greeting cards and having them onhand and then before bed or in the morning quiet(if you have such a thing) drop a few lines in it and mail it out. That is what I do for my husband especially when I'm missing him.
There are so many soldiers and marines and airpeople that do not get support from their loved ones at home that they need to know that for a few minutes that day someone gave a damn enough to send a card or package.
Please don't think I'm trying to lecture you personally because I'm not at all. I just want to encourage everyone that is thinking about it but still has hesitation.
