Ron...you need to pay a visit to your GP. He will be able to help you. There are lots of medicines available these days to assist people like yourself. There is no shame attached to having your condition and nobody else need know that you have visited your Doctor...just him and you. You will feel better just having gone and seen him. Believe me, because I have also suffered in the past.
If you have a partner or close friend, that you can trust, you might also like to consider speaking to him or her. A problem shared is a problem halved, as the saying goes !
I hope I have been of some help.
