Remember that your depression is strengthened by your apprehension and misplaced distrust of a proper mental health professional.

Secondly, start to remind yourself that people aren't your "friends" if they are unwilling to try and pull you up when you are down. "Fair weather" friends are not people you should want to, or need to, associate with. Yes, it hurts like hell to admit to that realization about a person, or persons, but it's the first step to overcoming that need for people that you do not need.

And remember, you are never alone. It's the depression that wants you to feed into that horrid feeling, and it's only you that can overcome.
