Oh honey, no, that’s totally understandable. I do not know the circumstances of why he killed himself, but it was a selfish act. It might be that he was in such pain that he saw it as his only option, I don’t know. It is not inevitable that you end up like him. From your posts, it sounds like you are getting help. I would try to find people who knew him when he was happy and had zest for life, so you can get a more accurate picture of who your dad was.
No. That would be difficult. Actually, for being 38 years old I have t been to that many funerals. It’s usually deceased cuz of old age. Grandparents/uncle/etc.
It doesn’t make you cold hearted to be indifferent to your father. Its a coping mechanism so that you will not be devastated by what happened. I lost my brother to suicide as a teenager and it ruined me. I believe schizophrenia developed later in my life because of the stress from that day. Stay strong and live everyday with gratitude!
I haven’t had family kill themselves, but a couple of my friends have killed themselves. They weren’t close friends, but I liked them, and both times I was completely caught by surprise when they killed themselves. If they gave any signals of what they were going to do I missed them. I wish them well in the afterlife.
