Welcome to PC. It is very difficult and a process i would say. First it is a process of self acceptance and trying to rid yourself of the shame that comes with it. Telling others who are safe and supportive can play a big role in getting rid of shame.

Do you have people in your life that you feel will be safe and supportive. By safe I mean non judgmental. If you do have such people the only way is to just tell them. I think I have depression and here is why. Explain to them what symptoms you have and how it affects your life. I find that explaining what it is really like for me and not just saying I have depression goes much further. This is what it is like for me - I have no energy and no motivation, I am not interested in things I am normally interested in, I can't seem to get out of bed, I don't shower......whatever it may be for you.
