Wow. Your diet is extremely unhealthy. Your body isn’t getting the nutrients it requires. Consider going through the application process and getting some food assistance. Buy yourself some fruits and vegetables before you get cancer or diabetes; not to mention wrecking your eyesight, losing all your hair, and developing some weird neuromuscular disorder. No shame.
Also, I bet you could contact a medical school to help get you an affordable vasectomy (like poor people near a vet school can get their pets treated and spayed/neutered for reduced cost). If that’s the best you can feed yourself, you’re going to want to get that taken care of before there are children to feed too. It’s just good sense.
