I'm sorry that you're going through this. First, I'm sorry that your first relationship was so traumatic. Your ex may or may not have known she had it - you can transmit HPV without symptoms, and many people don't get symptoms.
HPV is incredibly common - about 90% of us will get it at least once in our lifetimes. The good news is that it clears from our body, usually within 2 years.
You may get more warts after these, or you may not - there's no way for us to predict this.
If you have sexual partners within the next couple of years, give or take, you should tell your partners, and definitely wear condoms. You'll probably be surprised at how many of your partners will be "Oh yeah, I've had that, too." Your partners might also have had the HPV vaccine, which will offer a lot of protection, too.
I'm saying hope is not lost here.
I don't know why you don't have friends, or why you're so lonely. I know it's a pandemic, and depending on where you are, things may still be on lock down to various levels. However, you can still get counseling, which I absolutely recommend. Many are doing telemed appointments, or video appointments. Please talk to your doctor if you need a referral.
Also talk to your doctor about the HPV vaccine, which recently was FDA approved for people up to 45 years of age. That won't cure this infection, but will offer some protection against the more common strains for you in the future.
You're going to be fine. I promise.
