Trying hard to stay positive

So... long story short, all of my friends who I met in high school are pregnant (we are a group of 4 close friends). One is 20 weeks and the other 2 are 12 weeks. The two who are 12 weeks have only told me so I'm having to keep it to myself for now (obviously except for you guys). I've just started my buserelin injections and I have my first scan on Thursday. I'm really trying hard to stay positive. After my fresh transfer failed I was so sad but I've put most of my hopes on this FET working. I'm so happy for my friends but I have proper fear of missing out and generally fear of it not working. Sorry for the rant. I'm just struggling a little at the moment. I want it so badly and yet I just find it so so hard.
