Don’t know what’s wrong

I’m really not sure what’s wrong. Lately I’ve had a constant headache and stomach ache. For four full days. I’m also been really emotional to the point I feel like crying or wanting to kill myself over simply a change in attitude by some one. I haven’t been going to school this week and today i tried to but I was hurting so bad I felt like I was going to vomit and couldn’t think straight then my teacher said something mean towards me so that made me want to cry then i had a complete break down a few minutes later when a teacher asked me what was wrong. I really hope I didn’t make a scene to my other classmates but I probably did. I then went home and the principals assistants told me i should see a doctor. And im fine with that but my mom sucks so much at following through for making me appointments and such. Plus my military id for my insurance expires on the tenth. I guess I’m kinda just ranting because i know no one will have the miracle answer for me. I already know I have depression and anxiety and ive been on my period for the past couple days but it has never made me like this. I always simply have cramps on the first day then perfectly fine for the rest and the stomach aches I’ve been having don’t even feel like cramps all the time. I don’t know. I’m tired of living
