Help! Please no judgment

I just found out that I am pregnant with my second child. My husband, 3 year old and I live with my mother and sister because neither us or my mother is financially stable enough to afford to live without each other right now. We split the bills and help each other survive. My question is, how can I save space so that it does seem so cramped since we are unfortunately stuck sharing a room. Please no judging, I am doing the best I can. My husband is on disability and cannot work and I am also unable to work due to extremely severe anxiety disorder, also I am my husband's caretaker so I am not able to leave him alone which is why we are short on money.
