I have had crush loong time to same girl, we had fun yesterday at party and today i finally decided "now i do it and ask her out"

Okay, so i asked, as girl is really shy, i didn't followed all seduction rules and asked her out "softly"

Hey, as I yesterday said at party that it would be awesome to get known each other way more better. Would you be interested to go eat out some day?

She answered:

idk, i'm been just so depressed and stressed about school. sorry :( :( :(

So i asked her

Does this mean "Never" or "Not now"

And she answered

Not now :)

What this basically means, does she said it like that so i wont be so sad, or does she wanted left door a bit open if later, or something else?

I don't want be needy and "chase" that girl or waste any more time to her, i had just really strong crush on her, and I do not have had ever girlfriend.In fact, that was also my first time when i ask someone out

Life goes on and better forgot that girl, or should i still maybe little keep trying that girl?

Maybe just install tinder and "revenge" for that girl with trying get some other girl?

I'm 19 and girl is 18.

Edit: I planned if i send her this now, what you guys think

You told me about depression yesterday, i felt that you maybe do not want to talk about it, but really must ask, how long you are been depressed and you feel?

If you have even little feeling that you want talk (even if its hard) or need help, i think i can surely help you with it, even when it cannot be fixed in day or even at month. Even when we do not spend a lot time together, you are still become really important for me, and i do not want that you need go alone all shit that depression causes.

When i was really depressed, most messages and contacts annoyed me. If you feel like that, ignore this or tell me if my messages annoys you. I totaly understand it. But anyways, if i can help even little, let me know :)
