my friend, who seems normal and happy in general, is going to prison and has to serve 4 years. he was on the phone with me and said he wanted to kill himself and i told him not to. i am scared he eventually will before he is sent to prison. is this normal?

also, i am disgusted by his crime so i do not even want to be friends with him anymore. now i feel things are awkward between us because of this whole prison scandal. i am scared that if i end our friendship, he will kill himself.
