Need advice preferably from a girl!

[imjack]

Im a Senior in high school at the moment. When a Freshman, one of the first people Ive met was this girl. We became friends, from that moment on. We talked everyday, however sophomore year came. We started to talk less, but still somewhat frequently. Junior year came next, we barely talked. I've been going through things myself, I've been incredibly anxious and stressed the last two years, and have to a degree withdrawn from certain situations, and aspects of life. Not meaning that I wanted to. In fact I didn't want to. I did not mean to distance myself from her. I've been trying to resolve my issues, or at the least put them aside, and enjoy of the time I have left.

I was wanting to talk to her, in person , to just say that I didn't mean to distance myself from her. That I still wanted to be close to her. I havent seen her at school at all. And the real problem (at least I'm seeing it as that) was when she, after months of not talking posted on my wall on Facebook. "How are you? Miss ya!". During the time we have been talking less and less, she has done this every now and then (similar posts/messages but they'd last for hours/many posts). However this time, fully knowing and wanting to change the situation that was between us, I replied to that saying I miss her too and I was good, etc.. and asking her how she was and she replied back, saying how she was, at that point I asked her if I could talk to her sometime. No response. Its been 1 week. And she's on everyday, and is active (posts, comments, likes other things).

Now I dont know what to do next.
Should I message her and ask her again?
Should I wait a while and then message her(since its been roughly a week, and Im going on a 4 day trip the next week(she's not going tho))?
Would that seem like too much or "desperate" (since I technically already asked)?
And if I message her what should I say?
Just straight out ask her again (Ive recently asked her how she was, so saying that seams repetitive to me)?

What I was thinking is message her, the day after I get back from the trip, Sunday. Ask her whats up, and see if she would want to chill sometime, and catch up. Does that sound decent? or would you suggest something else?

It's alot I know. I just dont know what to do, and dont want to loose the friendship.
(I do like her, but I think that its best to wait for a while, til I bring it up)
Btw, I do not have her number.
Any advice or insight on this situation would be greatly appreciated.
Thanks In Advance!!! :)

You've already asked her once, no need to ask her again. This time, just do it.

Just shoot her a message. You should probably do it before the trip, my gut's saying no need to add more time to the distance, and if she doesn't want to talk you've got 4 days to yourself on vacation (:

Your message could probably be something like hey, been thinking about how we used to be real close and I really miss that so I was hoping I could get your number so we can text and hang out sometime.
Figure out what you're comfortable with in typing out your message and hit send (: good luck!

Is there any of her friends which you might be close with? I guess that often works out pretty fast and well.. haha..

K you are missing attraction. Attraction dies out over time. You go to the same school. Just start talking to her and create attraction. When she starts showing that she likes you. Ask her out
