Short version.. Rant alert

Basically, my friend who live a way away has been questioning me about why I haven't been 'keeping her involved' in my pregnancy... And asking what's wrong with me and why I don't bother and how come she doesn't know anything ... 
Truth is, I live 100 miles away, I have no Facebook or Instagram coz of my job, we actually haven't text any less than usual and she didn't text me for a few months I never really though anything of it people's lives are busy !
I've always been there for her through thick and thin, but atm I'm working full time, 34 weeks pregnant, ill, and knackered and I don't know how she want me to involve her? Our texting never went quiet, I've had no scan pis since 20 weeks, she hasn't asked anyway!? And when I said calmly "look... I'm just knackered and struggling a bit I'm not leaving you out I haven't really involved anyone just getting through the day I can do without this! " she COMPLETELY flipped at me... Swearing, she's not gonna bother, her nans ill and she has day to day problems ..I'm not the only one with problems (I never said anything about having a problem), blah blah blah I'm out of order , yes your 8 months pregnant and no nothing about you... And so on ...
I'm probably just hormonal and know I shouldn't care but I have been on The end of the phone for as long as I can remember, I have stuck up for her when she had a baby at 16 and protected her against everyone I know, I've never not been there and as soon as I'm a bit quiet coz I'm knackered I get that!
Seriously actually quite upset and just needed to rant and don't even expect replies but I'm torn between not caring and concentrating on my child and being gutted.... Urgh life eh?
