Welcome Anchor

You're right to seek out support for yourself and I hope this site helps. You sound like you're setting healthy boundaries for you and the children and if you're not already you may want to consider speaking to a therapist. A face to face support group for significant others/family members may also help. The book in my signature is written for spouses/family members of those diagnosed. It's excellent and I highly recommend it.
I hope your husband decides to manage the illness, but you're right you can't force him to take his meds etc. etc.
