For sure you are not "crazy", and I understand your main concern is the natural maternal instinct to protect your kids from harm. Nevertheless, your fears have no scientific basis -- and I have a suspicion you know this, intellectually if not emotionally. I will explain some of the science behind lack of risk to your kids -- but if your fears persist thereafter, you may need to address the potential emotional and psychological reasons for your irrational fears.

First, your HPV indeed probably is gone. Almost all HPV infections are cleared by the immune system within 1-2 years, so it is unlikely you still have an active, transmissible HPV infection from 2013.  Second, even if you had it, there would be no risk to your kids. The genital (sexually transmitted) HPV types are simply not transmitted except by sex. Even after years of sharing bathrooms, kitchens, towels, eating utensils, and living the the same household with infected persons, nobody in those households catches HPV (except in cases of sexual contact or abuse). There is simply no risk to your kids from urine on the toilet seat, or by touching them after your hands have been in contact with your underwear or genital area.

I hope this information helps reassure you. However, if you remain worried, speak with your physician about it, with an eye toward possible professional counseling. Your closing sentence shows this is truly a serious problem for you. I suggest it from compassion, not criticism.

STDs, including HPV, are not simply infections that happen to involve the genital area. The bacteria and viruses that cause them evolved that way because they cannot be transmitted by easier routes, such as simple touching or superficial contact. For those transmitted skin-to-skin (HPV, herpes, syphilis), they must be massaged into susceptible tissues or have prolonged contact. That's why genital warts and herpes generally first show up at points of maximum friction during sex (penis, vaginal opening, labia minor) and uncommonly on nearby surfaces like labia major, pubic area, or scrotum -- even though sexual fluids almost always come into contact with those areas during sexual activity. (Fluids tend to be smeared all over the place, right?) But infections only take hold in the more intensely exposed spots. Biologically, this is exactly why these infections are STDs and not transmitted by more casual exposure. It's also the main reason your kids are not at risk in the household, and why even crawling into bed with you -- even if that happened soon after sex -- carries no significant risk for them becoming infected.

Is the risk to household contacts zero? Probably not -- there are few absolutes in biology and medicine, and the rare patient shows up with genital HPV despite apparently honest stories of no possible sexual exposures, so rare HPV infections may be acquired nonsexually. OTOH, STDs simply are not seen in kids and household contacts of infected people, so any risk there is extremely small. Common sense hygiene is, well, common sense -- and I would recommend hand washing after toilet (duh) and probably against your kids hopping into bed with you when the sheets are moist with sexual fluids. But even that is mostly to prevent colds, diarrheal disease, and common skin infections (staph, strep, etc), not STDs.

On top of all that, also remember my opening comment:  It is unlikely you still are infected with the HPV you had two years earlier.

And you need to look at genital HPV as normal, just part of being a sexually active human being, both for yourself and your twins. It is unavoidable. Your kids will get it someday once they become sexually active, but until then they are not at risk. They should be vaccinated when they come of the recommended age (9-11 years old), which will prevent infection with the 9 HPV types that can cause the most trouble, making it likely they won't go through experiences like you have had since your abnormal pap smear.

As I said above, your immune system will suppress your infection, i.e. yes, you will "beat this strain". HPV DNA sometimes persists for life, with a potential to reactivate in future years. That may be what resulted in your abnormal pap. A new HPV 16 infection would be uncommon at age ~40; it's likely you were infected many years earlier. However, future recurrences remain rare, and the chance you'll ever have further trouble from it is very low. Follow your doctor's advice about follow-up exams and pap smears, but otherwise please do your best not to worry about this.

That completes the permitted two follow up comments and replies, and closes this thread. You can go forward with no worries about your health or your kids' on account of your HPV infection. It's a done deal! Best wishes.
