You don't need help with shyness, honey. You need grief counseling. I know that a lot of people can feel ashamed or embarrassed about seeking professional help, but loss is a tremendous weight on someone's consciousness. Time alone does not heal this hurt, no matter how many times people like to say it... it's simply not true. I know this from experience.
It sounds like you just need to talk to someone, so dig through your health plan to see about getting a referral from your Primary Care Physician [if you have one] If not, look for a mental health clinic in your area.
It takes a lot more strength to ask for help and try to get better, than it does to put on a brave face and simply 'carry on'.
