I just need some advice please 😔

I had a ectopic in December and I miss my baby badly even though the pregnancy was so short I still love her or him deeply until this day. I'm in college right now and there is this girl in my class who sits like 2 rows down from me and is 16 weeks pregnant. I'm not selfish at all or angry at her it just makes me super depressed inside and sometimes I just wanna cry. All I hear is she talks about her pregnancy and how tired she is, how she craves, a lot, and some people in the class just talk about babies to her sometimes I keep quiet but it just bugs me cause it hurts after losing a child. I would of been probably 6 months by now and how can I just ignore it and not let it bother me so much it's just hard 😔
