Am I overreacting?

So. For the last 2-3 months (late January/Early Feb) I have been using all my time off - weekends, before and after work - to help my friend clean out a spare room in her grandmas house so that I could move in. Her grandma is kind of a hoarder, she had boxes and bags of glass with furniture carelessly just thrown on top, going all the way up to the ceiling. (The rest of the house is also like this, so it took a really long time to clear out because we had to find places to put shit) and we had to move the 150lb furniture by ourselves, because when we asked her grandmas boyfriend to do it-weeks went by and he didn't. 
So basically, it just took up a ton of my time and energy, while also working full time and going to school part time. 
Last week, we got it cleaned out, we shampooed the carpet, and assembled my dresser and desk; about half of my belongings are there in boxes. And I have already reserved and payed for - a truck so we could move my mattress in. 
Well yesterday (4/20/17) my friends grandma posted on Facebook about my friend moving to another state soon and she was pissed because she wouldn't be able to see her grandbabies anymore. So I text my friend and I said "you are moving to Oregon? That's awesome! When?" (Both of us have been wanting to move there for awhile. So I was happy that she was finally able to do it). And she said she was moving in June. This June. 
And now I'm pissed. I'm not pissed that she is moving. I'm pissed that she did not even mention this to me. There was no "hey I'm looking into moving Oregon, so you should find another place to live." (Her grandma will kick me out once my friend is out) so now. I have 70% of my stuff at her house. Fully assembled. After working on it for months - and after 1 month of living there, I'll be out on the street. She did not give me ANY heads up. Now I have nowhere to go. I don't have enough time to find a roommate and an affordable place to live. So I will likely be living in my car for a few weeks. 
I told her that she completely wasted my fucking time. I never would have started moving in, if I had known this was happening. I feel like it was extremely inconsiderate of her to say literally NOTHING. I was over there with her every day. For months. And she never fucking mentioned it. 
Am I overreacting? Am I crazy for being pissed at her? I have BPD, so I tend to have very explosive anger and emotions, often over absolutely nothing. I haven't spoken to her since yesterday; just because I'm still really angry and I don't think I can communicate with her without hitting her or name calling. So I'm just not.
