You can publish on Smashwords, which will get you in all stores except Amazon and GooglePlay, but this does include B&N, Kobo, Apple, etc., plus some libraries. Payment is via PayPal, which means you can link to a credit card instead of a bank account. Unless your credit is horrendous, I know you can get approved for credit cards online. Link on payment is here:

Uh, to reply to the emotional content--I feel your pain. Truly. Nobody I love reads anything I write, not even the two family members who did for a little while. And it hurts--a lot. But dealing with that sort of thing seems to be part of living. It's a reminder to me of how important it is to be supportive of those we claim to love.
Your ongoing situation, however, seems abusive in nature. This is from years of being an abuse survivor and the resultant counseling. If you can change this, you should. A relationship where someone is treated with contempt isn't good for either the abuser or the abused.
That's not to say that the two things are linked. Go ahead and explore the Smashwords thing. But afterward, perhaps take courage from this to explore whatever counseling options you have. There may be some inexpensive choices available, particularly if you can become involved in groups like Al-Anon. They even have a toll-free number: 888-425-2666. I wish I had more resources to offer, but so much of what there is depends on where you live.
It's your life, and you certainly don't need my permission for how you choose to live it. But please, at least consider it. The recommendation comes from experience and concern, for what that's worth. My wish is for you to be well, at least within the limits of what you can achieve.
