Experienced an chemical pregnancy at 19

Context : I am 19 years old college student living with my boyfriend. I deal with POTS and endometriosis.

Late august I started to get weird symptoms. I dealt with an eating disorder and hadn’t had my period in 8 months. So these weird hormonal Symptoms i assumed were pms and my period coming back. However they were intense. I tested twice. Both negative. I tested two days later and had multiple faint, but visible positive pregnancy test.

However a couple days after I got my period. I assumed this was a chemical pregnancy. Learnt about them in nursing school and it sounded like text book.

I told my doctor she didn’t care and said it shouldn’t matter cause im 19.

However. Im dealing with severe mental toll. Im crying every single day, Im super depressed and can barely sleep from the stress. I recently found out a friend was pregnant and was SO angry because I was jealous that someone got to have what I didn’t that it ate away at me. I couldn’t even be happy at all for them.

No one really understands cause I’m young and it sending me into a depression and anxiety.

Any suggestions would rlly help💗
