*update*Well today was way more stressful than I was ready for

My husband and I have been ttc for two years and one month. We decided to try an IUI this month. I took my ovulation test this morning and the surge line came up before the test line! I was so excited and nervous, I called my husband who works nights to tell him he'd be making a trip to the sperm wash before he could come home and go to bed. Then I got ready for the day before I called my OB's office to let them know today was the day( they told me to just get there as soon as the sperm was ready and they would fit me in). I was so nervous I asked my best friend of twenty three years to meet me for coffee (I had tea to keep my nerves down) before I could pick up the washed sample. Everything was going so smoothly so far and my best friend was able to come with me since my husband had to get to bed after giving his sample. We got to my OB's office and I checked in at the front desk telling them "I have my husband's sample and I'm here to have my doctor administer my IUI. ". The receptionist let the medical assistant know I was there and said she'd be out in a minute to get me. For those of you that don't know, they tell you to get there as soon as possible because the sperm needs to stay warm and you have an hour. So I picked up the sample at 11:15 and they reminded me to keep it warm so I stuck it in the waist band of my leggings under my sweater, got to my OB's office at 11:25, and at 11:50, I started freaking out. I went up and told another receptionist I had my husband's sample and though I understood they were busy, I only had a limited time she said she would check with the assistant as I was walking back to sit, I heard the receptionist say " Kelly I. is-" then get cut off by the assistant saying "oh I know, I'm getting to her". It's now noon and the assistant comes out and gets me, clearly aggitated, she says to me without even turning to look at me "so what's your question?And why couldn't you have just called and left a message.", I said "um, I have my husband's sample, I don't have any questions, I just need my IUI.". She then asks why I didn't call ahead and let them know and tells me I should be holding the sample against my skin to which I respond, it's right here pointing to my waistband and I did call, she responds "that's not what I heard"(I'm starting to cry at this point, it's 12:10). She took us to an exam room and very unceremoniously told me to take off my bottoms, keep the sample under my arm, get on the table and the doctor would be in to see me in a minute. I laid down on that table and cried to my friend, called my sleeping husband who I wanted more than anything and tried to think how we just spent $150 to have a sperm wash and that the sample was ruined and how to remedy it. My sweet OB came in at 12:35 and asked how I was and I immediately started bawling and explaining how there had been a lot of miscommunication and I was worried the viability was compromised. She's the best and calmed me down pretty quickly letting me know as long as I had kept it warm it should be fine and she would even put some on a slide and make sure when we were done with the proceedure. She was so funny and sweet the whole time knowing just how to help me stay calm. Our sperm was healthy and looking good but I am still really irritated with how the medical assistant behaved. Just trying to put on my Zen now and keep calm so this IUI takes. ** AF showed today, a day early and I am so frustrated, especially at that medical assistant. I don't know what to do from here. I'm thinking about deleting the app and just stop trying all together. I'm so tired and sad over two years of trying I feel like I'll never be a mother just some who takes care of other people's children and watch as they have more and more and I have none. I don't want to go to work today, I'm a full time nanny for three children the youngest being just over a year. I'm not sure I can do my job anymore, I've been taking care of children my whole life at this point and now that I can't have my own I don't know if I can stand the heartbreak of taking care of someone else's.
