Talking to a psychiatrist is just going to cost you money and most of them are atheists so they won't be much help.  Stay busy by finding something to pour your heart into whether it be a job, charitable work etc.  Spend some time around people who may have problems of their own and be a friend to them.  Read good books, spend some time in prayer and don't be afraid to speak to a priest or nun and tell them your thoughts as most religious have training in spiritual direction.  Find someone nearby who may be hungry and give them some food.  Realize that your situation isn't as bad as you may think it is and spend your life in a worthy cause.
