feeling low today

i lost my dad in october last year i did post the circumstances of his passing on the yt site where everybody was so kind, well as some of you might remember my beloved dad died suddenly of a heart attack in his bedroom, we had no warning , and my poor dear mum found him dead on the floor, i live only a few yards from there house so i was soon there and saw my dad dead on the floor and my hysterical mother laying over him screaming, as i am sure you can imagine i still have flash backs of that night and my heart screams with pain, but over the past week i am virtually not sleeping, i feel so stressed about everything , most days by body aches with the stress i feel even everyday problems to me are magnified i feel likei cannot cope with anything, please do not get me wrong i am not suicidal i love my family way to much to do anything silly i guess i just needed to tell somebody i cannot burden my mother with my feelings her pain is bad enough anyway thanks for listening ladies.
