Hi again peppy,
Can now see why you need some chat and general B&S.
Please accept my condolences and heart felt compassion.
You appear to have lost both your parents in short period of time - nothing takes away the pain, or your tragic sense of loss.
If you are female, I imagine your guilt is based on the teenage arguments, her coming to terms with her husbands death, her being the only 'brick-in-your wall'.
Please talk to your doctor and also go to the library and get some books, on the journey through bereavement. You will read about the various emotions you will encounter and find advice with how to cope. They cover anger, disbelieve, guilt, along with the rest of the emotional 'big-dipper'.
I wish I could give you a few simple words or encouragement - but I am not a doctor, and I really reccommend you seek out proper advice and assisstance. These people are trained to help you, and will be able to recemmend you to support groups.
Please get some help, there is no shame attached, it takes a big person to ask.
Chin up hun, and more help just look in Body and Soul.
