Today I start a new life

Just to introduce myself, I am a 28 year old nurse from Missouri. I have had a very hard year. In November my husband for six year (together for 9) and I separated. (I had the discussion (my choice) for a divorce last monday night). I lost 30 lbs in 3 months due to poor eating. I then gained back 20 in a matter of a few months. My grandmother was diagnosed in March with terminal lung ca. We have gone through chemo and radiation to slow the progression, but she has been given 18 months (give or take). My aunt was diagnosed with severe aortic valve regurgitation and had to have valve replacement Aug 22, 2012, then suffered a stroke (thrombolytic) from the artifical valve on Aug 24. My mom has Lupus and was diagnosed in May with synaptic reflex dystrophy (which is a crippling disease). So right now life really sucks. So i have decided to turn a new leaf and try to make a drastic life style change with all the depressing things around me. I am also a smoker and I am going electronic on Sept 1st. I really need some support.
