Would you say I’m stressed? 🚫Please do not scroll I need answers, im going CRAZY 🚫🚫

This guy I have been seeing for some time is back and forth with me and his baby mother. He broke up with me this week, I’ve been sad and crying for the last two weeks, drinking and occasionally smoking. My weight has been fluctuating between 158-163 in this week, I usually stay around 165. Which it usually doesn’t do that much of a difference. I haven’t been hungry, I forget to eat or just don’t want to. I have no drive, all I want to do is lay & cry. I went to my friends house which is where he lives and I saw her car over there 😭😭. My period is 10 days late, I’m having stomach pains and cramps, I also have gas and its causing me to cramp, I’m fatigue and all 10 test since day 3 of my period has been negative, even the digital one. I have no period symptoms, no sore breast or anything. What is wrong with me. Mostly is what is scaring me is the no period & my cm milky white.

Also, the drinking and the smoking was the week before my period was suppose to come & I never suspected it because we always use protection & I’ve been using only condoms for 3 years without a worry.
