Welcome, Evita! I am so sorry to hear about your mom, and I do know how hard certain family relationships suffer when we "fade" or "leave". You will find a wonderful support group here, as you seem to already know. I have been visiting this site for over 4 years and it has helped me in my transition (believer >>>>> unbeliever) immensely. Take care and feel free to talk about how you REALLY feel anytime. There are always some people here who understand and can help.
Warmly,
Trudy
