My depression in the past 2 years has split into why's,whens, and hows. Its uncontrolable, and very depressing.

I'm always wondering how do you know someone really cares?
Do therapists/pdocs really like you?
Why do people seem to get lust and love mixed up?
Is sex all that strives relationships?
When will I see the light?
Why do I think these things?
How can I stop it?

These are a few of many questions running through my mind, despite its irrational out look I can't seem to stop. This is an issue I'm dealing with in therapy now, but as 1 question states I dont know if she (my therapist cares)...its all doubt,..I know depression lies...but these thoughts are overwhelming in public I cry when I ask these questions as I look at other ppl...wondering...when will I be them...NORMAL...

When did you all see the light,? And if you havent...be with me on the journey,...we're on a train and soon to get off...with hope!
