Happy birthday! I'm so sorry that it's such low times for you, healthwise and relationship-wise. I haven't read here for a while and was very sad to see that the good R you had for a while, is no more.
My birthday was yesterday. My S day was 1 week before that (a year ago). This year, I celebrated with a new 'family' and had a great time. I didn't even think about the past or experienced any difficult feelings. You will be okay.
Take care of yourself and your heart!
