Hey!
I am so sorry to hear about your losses!
It is very hard to go through this grief. People turn to whatever they think will comfort them--and it's not always the best thing.
thinton, do you have a grief support group that you are taking part in? This can really help you to get through the process, and often these groups are no charge. GONNABE165, the same would probably help you also. I hope both of you are finding some support through your family, your community, or your church if you have one. Sometimes seeing a doctor or a therapist might also be helpful.
Maybe until you are feeling stronger, you could concentrate only on not gaining any MORE weight, and on eating healthy, nourishing foods--not sugar, not junk--good foods. This would be a good way to take care of yourself. Of course, eating in a better way might also help you to lose.
As for exercise, just going for a walk is very good exercise to start with. If you have some exercise videos you can do, that might be good too. Don't think you have to do something big and strenuous to exercise--the point is to be more physically active.
You can get through this sad time without gaining more weight. Please hang in with us--we'll try to help if we can.
