when can you say you're depressed?

When can you say that you are depressed?

Can I say I'm depressed right now...

...even if I know the world is not against me?
...even if I know the Lord looks upon me and takes care of me?
...even if I know my family loves me?
...even if I'm happily in a relationship?
...even if I can really tell who my friends are?

When can you tell?

When...
...a friend don't call or text back?
...a friend leaves you behind?
...a friend insults you to your face even if they think otherwise?
...you know you're insulted but you just let it be because of friendship's

sake?

...you think you're a failure but they tell you, you're not?
...your being scolded by your parent but then says they're not?
...you're too sensitive to the people around you?
...you can't think right and just feel as if nothing seems your way?
...nothing seems your way. Period.
...your sibling talks back at you and your parents let it be.
...you help someone but apparently, your help is not wanted.
...you gather along with so-called-friends and tell you, you've "missed"

some happenings even if you know you weren't informed
or you knew but you weren't invited?

...you just know you weren't invited at all.
...a friend lies to your face though you know it's really a lie.
...you're being blamed for everything that had happened.
...your good works are banished once you've committed just one mistake.
...all you can do is think why this is all happening.
...you know it's all not that bad but still.. still...
...your friend promised to go with you but ended up going with another

person.

...you clearly need help but no one answers your cry.
...you are good at masking your sadness deep inside?
...you know you are not alone.... but you feel you are.
...you know the Lord is always there but still, there's a pang.

Why?

We do know that things happen for a reason... can it happen without depression?
