5 if my friends just got engaged and I’m battling cancer

5 of my friends just got engaged literally this week and I’m so so happy for them but I can help but feel sad for myself. I just turned 23 and about to start my second round of chemo. I lost my very toxic job (so kinda good in a way) and I’ve never been in a relationship. Never even kissed anyone. I feel pathetic. I had to go wig shopping while they went wedding dress shopping. My parents, aunts, uncles, grandparents all got married and had their own place by 23 as well. I’ve had chronic health issues all my life so at 23 I’ll be going through menopause for the SECOND time. Chemo may also prevent me from having children. Im so upset I just don’t know why this is all happening to me. I’m trying not to compare but it’s so hard when I’m literally bed ridden and have nothing to do but think about this. My dream since I was little was to have my own family but If I survive cancer my odds are slim. Any advice?
