Hello Vicky,
I am so sorry to hear that you have lost your mother. I lost my husband and I know first hand what it's like to feel so much pain you don't think you can bear it. You'll never forget her, but I promise it will get better and easier in time. I joined GriefNet (
GriefNet - A Community of Persons Dealing With Grief, Death, and Major Loss@griefnet.org) after my husband passed away and it was the best thing I could have done. It was free and there are different forums for those who have lost different family members, so the people you are speaking wtih are going through the same thing and are a tremendous source of comfort. There were also people online from all over the world so during those sleepless nights, there was always someone to talk to.
I'm glad you are here. I'm new myself, but everyone has been so helpful and encouraging. Don't be too hard on yourself right now, but you can take small steps that will help you a lot. Exercising, even taking walks will help with weight loss, but will also increase the endorphins in your body to ease your mind a bit and will also help you sleep. Sleep. Drink a lot of water and keep things like mini carrots and celery close by to munch while you're on the computer (a trigger of mine).
Hang in there.
