Struggling with CHF Diagnosis and Shortness of Breath

I'm not asking for medical advice I would like to know How I am able To powerwash my mother's house Which took me 3 days I have been outdoors in the heat And I am also painting the front deck of this house. That being said, I was diagnosed with CHF2 years ago. My heart was pumping at 20% then. I hate hospitals I'm tired of getting my arm poke they cannot find my blood vessels. Several times I have stopped taking my medication the last time I stopped for almost 2 months, Then I started having Anxiety attacks from Hell. That was a big mistake because now because now my heart is beating at 8%, And yet here I am working outside. The main medication that I take is Flurosemide, And 2 other medications. I was supposed to have a life vest Before I left the hospital the 1st time but I don't have insurance so they kind of let me go and I never got one now they tell me it doesn't matter it it will not help me. I smoke menthol cigarettes and I smoke weed, How am I still alive. And one more thing I have not changed my diet whatsoever I eat chicken fried steak mashed potatoes everything I eat ice cream and I'm not supposed to have more than 1 Leader of liquid in a 24 hour period, I have gone over one l leader Every day in the last 2 years in the last few days I have gone well over like 80 oz or more. I'm sorry one more thing 2 weeks ago I fried one pound of bacon and ate all of it And did It again several days later. I'm a skinny man 56 years old And no matter what I do I cannot gain weight Because all my blood vessels are shrinking supposedly. I am basically a walking dead man That's what 8% means to me So I'm going to live my life the way I want to live it. I cannot afford the healthy stuff Because I cannot work supposedly. Can anybody relate to this.
