what themorpheous said I agree with. The sad thing is that no matter what everyone wants to do to help, we are all powerless. It's truly horrible what is going on in Syria - my heart bleeds for all those poor people trapped there with nowhere to go.
My only very tiny contribution is to buy things I find from or made in Syria in the hope that my purchases might go toward someone that can help their own back home.
So sorry to hear about your friends. R.I.P. :(
