Jealous of my pregnant friend

So my best friend has just found out she’s pregnant and I’m so happy for her and she deserves it but not going to lie a part of me is so hurt and feeling hopeless because I want nothing more than to have my own baby. I don’t even have a partner so I’m not really close to having my own either although I recently made a decision that I will have a baby through a donor if I don’t find someone

Would love some advice from those who have had the same feelings as I have 💗
