Hey there mrsmac, welcome 😀. I understand about the needles, whilst I didn't have too much of a problem at the beginning, I found that the further I went into my cycle, the more I started to fear them. It was so strange!
My clinic had nice comfy recliners for us to sit in and have our BT's and I got to choose which arm to offer up each time (the illusion of control lol!). As for the stim shots, I found that if I iced before and after, I didn't feel them and didn't bruise. Just make a ritual out of it, like taking the time to sit in a comfy chair etc.
At the end of the day, you could look at the needles as a necessary step in achieving a beautiful bub. Best of luck to you.
