I can relate to your issues. It has taken a long time, but now I rarely share details of my personal life with people other than extremely close friends and family.

Maybe it isn't acceptance you are looking for from someone/anyone during times you are in pain, angry, stressed, etc. Perhaps you are trying to find someone who will listen, empathize and offer advice within your community circle.

PC is a good place for finding those things! And you don't have to worry about a backlash of gossip.

Just one idea now - try making changes at your workplace. Bite your tongue and silently tell yourself that you won't share intimate details of your personal life. Also, disengage from those who gossip about others. It is so easy to just get sucked right in. But that can easily lead you to start saying stuff you don't want shared.

Expressing your anger needs to be managed in a similar fashion. Remind yourself that it is damaging to your image at work and within the family. If you fell really angry towards a situation or co-worker - try sleeping on the situation before you respond. Our perspectives can really change after some hours of cooling down and resting.
