What to do when you're being ignored?

A friend and I were thinking about booking onto a holiday with a group of our other friends, and after having a serious think about my finances I decided I couldn't afford it.
I'm having a fairly rough time at the moment - I'm really struggling with depression, I've had drop out of university and drastically reduce my hours at work to help myself get back on my feet.
So adding the stress of saving up money for a week of 'fun' when I'm struggling to pay my rent doesn't exactly seem to be the kindest thing to do to myself atm.

And now my friend is ignoring me. We usually text one another all throughout the day, speak on facebook, talk on the phone and are generally in contact with one another almost all the time.
I looked at her facebook and I can see that she's been updating status' all week.
So I know that when she isn't replying to my texts or fb wall posts its because she is ignoring me. She's even dismissing the silly things we usually text each other like pictures of new manicures, jokes and general banter like that.

And I'm particularly shocked especially as she constantly tells me that she's always here for me, and she knows everything I'm struggling to get through. I feel like she knows how much I'll be panicking about her not speaking to me. And in the text I'd sent her saying I couldn't come on holiday with everyone I apologised for letting her down, but on second thoughts I know I'm not letting anyone down. But this silence is making me feel as though I am. I feel like I've been punched in the face.

It's not like there won't be other holidays. Right now just isn't the right time for me. But the fact that. I feel so hurt and I feel like she's punishing me for something that I don't have any control of at the minute.

Is it possible that her phone service doesn't work where she is or that she would like to relax and enjoy her holiday without dealing with a phone? This doesn't sound like punishment, rather it's what happens to most all of us when our friends go on vacation. Calm down, she will be back and everything will get back to normal unless you escalate the drama into a big deal.

I say relax, and continue to go about your own business. Let her be the one to initiate the next contact. You've made ample effort to connect with her. Reciprocity is important in any relationship. *If* she is actually ignoring you because you aren't able to do what she wants, then that gives you good reason to re-think your relationship.

Good for you for thinking through your situation so clearly and getting your priorities in order. I hope my kids are able to make sound decisions like that when they are your age. I hope things turn around for you very soon. :-)
