Becky,
I am sorry to hear of your losses. I suffered 3 losses within a few weeks and it has taken me about 2 years to feel "normal" again. Until lately, i just got through - did only what had to be done. If counseling is available, get it. I will be praying your fears go away. I have some of that, i am obese and have had a hard time getting back on track. I don't have any health concerns - yet, but i am a ticking time bomb for many things and we have two young children, one with a lifetime challenge of autism. I recall having some of my worst anxiety about not waking up during the time of my father's death, and not having anyone to properly take care of my kids.
