My husbands aunt killed herself last night

I'm at work and kept getting calls from my husband and his mom. Apparently his aunt who he was very close to shot herself last night. She beat breast cancer years ago and it unfortunately came back. She just found out and decided she couldn't go through it again. I feel so bad for my husband, his mom, and his cousin who just found out his mom committed suicide! I am sort of upset because I told my boss and she won't let me leave to go be with my husband. My husband has been crying and is very upset. I get off work in 3 and a half hours and it's killing me I am not there now to comfort him. Has anyone here ever dealt with a suicide in the family? I have never been through this and I know my husband hasn't either. His whole family feels guilty for not taking signs more seriously. Always be grateful for family people!! :(
