Where's my period?

I have an irregular period. One time I had my period for an entire year, once I didn't have it for 7 months. And it goes on and on with irregularities. Now that I have that out of the way. My period has been pretty okay as of recently. Although it's been freaking me out. I'm not pregnant. But my period has been showing up later and later each month. This year I had it: May 25th June 28th July 31st and lasted till Aug 4th So I'm supposed to be getting it right about now. And of course with my irregular period comes my irregular symptoms. Regular symptoms: Usually my boobs are so tender it hurts to wear a bra and a shirt. Mood swings Crying Salty and sweet foods Overly insecure Indecisiveness Lots of bowel movements Uncommon symptoms: Cramps Pain- when I do have pain I can barely walk it's so painful Bloating Fatigue But this time around. I only have bad gas, bowel movements, mood swings, salty and sweet food cravings, overly insecure and indecisiveness. My boobs don't hurt but they feel lumpy which is how they usually feel around this time. It's like I have all the other symptoms but not the one that actually tells me if I'm going to get my period. On top of all this, my grandmother thinks it just might be stress. Stress recently: Had to get a job transfer, boss then refused it, I had to call district manager and human resources to get it. Adopted father and step mom came to see me with their new baby. Baby cried all night. I did not get a good nights sleep. Had to pack to go to Gainsville with friends. We showed up and I had to sleep on the most unconfortable, dirty futon ever. I got super trashed and ended up drinking 6 beers, 7 shots of scotch. I threw up twice, threw my phone in the toilet, boyfriend helped fish it out and make sure it was okay. I was hung over for a while. Didn't realize they were going to drink again the next day. Ended up drinking 4 shots of whiskey and having 2 beers on this day. I picked up a snake from the bushes and held it, got freaked out that it would bite me. Put it down. I climbed on a ladder to a 9 foot tree and hopped in a lake 3 times. That was scary. I got a really bad adrenaline rush. Didn't get home till really late being a huge storm hit the lake house and there was no inside area. So we prayed not to get hit by lightning. The power went out 4 times. So then we finally went home. And didn't realize that another party was going on the next day. I Went to Timfest and didn't drink at all. But it was stressful because of the fact that I pass out in large groups of people and it gives me an anxiety attack. So I drank Arizona iced green tea in a can. And had a bag of chips. That night I had to pack and the house smelled like a gas leak. I almost went to light a candle before I told my boyfriend to check the stove and it turns out someone left the stove on. So I freaked out about me almost blowing us up. I freaked out because I absolutely hated my boyfriend's friends and I just didn't appreciate their company. We got into a fight but it was resolved and I came home to my grandparents yelling at me to hurry up and transfer stores. Also my favorite pair of heels broke, my computer broke before I went to Gainville and I had to spend 200 just to get it fixed and I'm right on cash this month. So where the hell is my period?
