Tired

I feel like I am going crazy most t II mes I feel like I am the only one in the world going thru this.I no I am not but it gets to me bad. I have no energy to do anything I wake up set up to edge of bed and I done I can breath I can barley get my inhaler. I have started peeing in a jug cause going the 10 steps to the bathroom is very scary sumtimes. Just to walk to the fridge I normally stop 2 times. Now I live in a small trailer. To get to fridge its 30 steps. I am to the point of giving up. I don't bath like did I don't wash my clothes or help with any house hold chores. I try like today I WA going to vacuum well I made it about 4 or 5 feet started getting hot I was done. Tried to start back a lil later barely got the vac. On i was out of breath and getting hot. Done for. What is it with getting hot it happen fast to I mean out of no where I am hot and I better set down then. The feeling I get is the worst. And then I got to pee right then and I mean right then. So I keep a jug handy. I am 56 yrs this is just no way to live or no way to die I don't understand slot of things and suffering is one of them. My gf who I live with has taken good care of me she has been there thru everything that's happened here at the house if not for her and her son I don't no what I would have done.but she is tired if taking care of me she thinks I can just get up and push thru it. I tried to tell her I can't but things get bad pretty quick. I tried to tell her I don't need to get up set but we end up in a big fuss and I don't have the breath to fuss. Not to mention I lose my voice all the t II me I get 2 words out ten my mouth move but nothing comes out sum tines its like that for days. I get so mad but can say anything I try and ppl just look at me crazy like. I guess I just want to no I ant the only one going thru these things? Am I
