My smoking family

There’s this thing that drives me insane. Basically, all my older siblings and parents smoke. So in total, 4 people living with me smoke and 2 others who don’t live in the same house smoke as well. We’re a big family and we’re struggling with money but it just angers me so much because I need to keep feeling guilty and shit about myself about the fact that we’re broke. And they keep spending and spending, and smoking allll the time. How am I supposed to live this way? I know it’s an addiction and that it’s not as bad as drinking or doing drugs but still, how are we supposed to ever STOP being poor or be able to live a normal life if this keeps going on? I can’t do this anymore, and they keep loaning money from me to feed their addiction. What’s even worse is that my dad is getting sick from it. He has shortness of breath, coughing a lot (to the point that he’s just choking) and he continues to smoke. And the others continue to buy.
