Raindrop.... I have not been on so hadn't seen this til today. The link above is for 211. You can also just pick up the phone and call the number 211... they give referrals for any and all type of crisis. There are many, many help groups available to you and your family. I encourage you to find a survivors of suicide group... the other attendee's will be going thru the loss of a loved one to suicide as well and will understand all the emotions you're experiencing.
Please, please remember this is NOT your fault. Once someone decides to commit suicide, it's only a matter of time until they achieve it.This was your brother's decision, and while guilt is a normal part of grieving, I again stress this was HIS decision and is NOT your fault.
I really hope you'll reach out and get some help working your way thru the grieving process. You don't have to go thru this alone. Hugs...
