I am locked in the hospital after a crisis which involved the police stopping me from SUI.. I feel I suck, I feel I am worthless and I feel guilty.

My BF (near to be husband) got offered a group therapy for relatives to people with mental illnesses

I know it is selfish and bad, but I am worried they will say bad things about us with problems and that my BF will reconsider being with me

I already feel like such an worthless thing

Please help
