What can i do to help him?

Hey i know that i haven't been posting latley but i've been busy with School (Barbering/Cosmetology,Institute).. It's a whole lotta fun but kinda hard work and way long hours.Anyways another reason why i haven't been posting for awhile is because im goin through some family problems.. To keep the long story short last wednesday morning and this morning i woke up with my dad yelling, screaming that he wants to commit suicide.. Yeah scary i know.. Basically i have no idea what to do except, if it happens one more time im gonna tell my old and new Bishop. Old Bishop from old ward and New Bishop because we moved during the summer and i really dont feel comfortable in this new ward neither does my mom. I mean, isnt some wards sapose to greet you when you are a new family in the ward..?
And basically i dont like my Bishop and im sorry to say that but, it's true. I feel like this new Bishop ignores me, i mean because he's talked and said hi to both my parents but not me. Anyways i really want to help my dad but i really dont know what to do except for what i just told you. And if that doesnt help i can call the suicide hotline. And so basically i've had awhole lotta drama this past month. And my mom thinks that my dad is saying that for attention but i really dont think so. And im sorry about this post being so dramatic and kinda sad but i couldn't hold it in much longer it's been eatin me up inside. And i know this is probably not true but whenever he saids that i feel like i have no one to go to and that no one cares. but i guess its ok.. Im sorry for this post of my blog but i really need some advice that i can get the more the better.
And anyways i hope that i can get some comments and advice soon.
And my apologizes for this sad post.
