The phone thing is simple. High maintenance ANYONE does not last 10 seconds with me, never did. If you are my friend then YOU KNOW I rarely answer my phone. I don't care WHO you are, if you are not my husband or my kids you are lucky if I pick up. I don't even check my vm's sometimes for weeks. My dear friends know this and they don't take offense. They understand that if I am hiding from the world it is because I am not feeling positive and don't want to spread that to them or that I am simply wrung out from MY LIFE and will be THRILLED to hear about THEIR LIFE when I have recovered.
I reply to texts when it is convenient but I do get back quickly. I used to text and drive all the time. Now I have trouble focusing from the small letters on my phone to the distances on the road so I DONT DO IT AS IT IS NOT SAFE. If it is someone like my kids then I pull over and reply IMMEDIATELY.
My sister and I skype (She is not in the US) and she is having a hard time and I just couldn't deal with it so I turned the skype off for weeks. She contacted her husband who contacted my best friend who finally called my husband so that my sister could talk to me. She reamed me out for hiding from her (she was justified to a great extent) but she also realized that for me to hide from her for THAT LONG I must have been growing through some hairy crap... so we cool now.
As for the cussing. It will be consistent with your level of frustration. I know you are probably tired out from being pregnant and all the stress this will continue to cause in your life, even happy stress is still stress. Don't fret too much on it.
As for your friend... just don't answer any of her calls/texts. If she can't *get* that your life is about to major big change and you are putting yourself first (for the last time for a very long time) then fuck her.
Stileto - I feel you on the whole working with incompetent peeps/being put in a shitty place thing... sucks ASS when your boss drops the ball and it is made to look like YOU are somehow failing.
