Feeling angry

I have recently been diagnosed and had a lumpectomy last Thursday.  I’m feel fine not overly sore but tired.  Mine was picked up on a mammograms so early and I’m very grateful and know how lucky I am.  I’m ok with diagnosis 1 in 7 my turn.  The issue is I’ve been through so much recently and I’m finding myself angry.  Well the last 2 days.  2 knee replacements, fibromyalgia, depression, late adhd diagnosis at 62, mum with dementia I’ve had to put into care, I sold her house without her knowing which is heart breaking - no help from siblings and that just this year.  Lol.  I had a breakdown a few years ago through work, got divorced, my dog died and I burnt my nachos the other day.  A bit of light relief.  There is more but that will do.  I’m exhausted keeping a lid on everything.  I’ve spoken to my psychologist who suggested Emdr.  I’m by myself and just so angry.  My kids have their own lives and basically my safe place is my home (with a massive mortgage) and my dogs.  I had started a wonderful new business but have had to put that on hold until I find out what happens next.  Which is next Monday.  This is not a why me post it’s a is it normal to be angry.  Not all the time but it’s scathing and my dogs have heard some words that I have never mentioned before.  I’m not really good at asking for help.  And was disappointed with the support I received with my knee replacements so reluctant to go through that rejection again.  I think maybe it’s the lack of control, not knowing where we go from here.  Again I know how lucky I am and whatever treatment (looks like radiation and hormone therapy and possibly another op and chemo if it’s travelled) I will gladly do and be thankful.  I guess I’m just bewildered and have no idea what’s normal and whats not.  And if I’ve honest I’m teary too.  Ok I feel lonely and unsupported as well.
