Most companies have an 'EASE' program with a 1-800 number for emergencies. They will refer you to a local therapist for the short term. These services are confidential, so they say. Your health insurance will have a list of covered mental services and providers. Going onto your health provider's web site will help too.
Don't be afraid of going. Let me offer some good advice. Therapy is good for the soul. My last was an 80 something woman who looked as if she was Yoda's sister. She was amazingly wise, asking a few questions and allowing me to answer myself into my own solutions. She kept me from going insane.
I've had 3 divorces in my short life, and I can tell you my emotional train is not on the tracks. My heart is out on the end of my sleeve and sometimes I feel a fart joke can make me cry. Therapy helped....friends help too. Have a couple lined up that you can call 24/7.
One co-worker, Chris, back in the mid 90's walked up to me at work and said, "I hear you are having a tough time with your divorce". I stared at Chris blankly not having the energy to tell him to "Fook off". I handed over my numbers and he walked away. The following Saturday I found myself host to an especially difficult pity party and my .45 Colt. Upon placing the weapon to my head the phone rang. I thought, "Damn it, I can't kill myself without interruption". It was Chris calling to check up on me. Chris saved my life, he was a complete stranger at work until then.
Chris called me each day for months and became the center of my recovery. Each of us need to take on the role of Chris for someone in our lives.
Find a good therapist, rely on your friends, seek God. If you need someone to talk to, I'll volunteer.
