First off you are not crazy. And second of all, I experience something similar.
What has helped me cope is, working out, eating the right balances of food, and watching the amount of sugar I intake prior to that point in my month. And for me, as soon as the bleeding starts, all of those feelings going away. Now, I have a period tracker that helps me note when I am about to have my period, and when it is most likely that I will ovulate, etc etc.

Being aware and noting down how you feel exactly on those days will certainly assist with controlling those feelings.

Every single month I experience similar symptoms as you. Where I differ is it only happens for one day just before my period starts. The way I feel includes disliking my family, disliking my husband and having very strong feelings that lean towards hate.

Just after having my daughter, I had extremely bad bouts of resentment just before my period and I was very very moody. I ended up going to my doctor to ask what was going on. It turned out that I potentially had PMS disphoria. Since I cannot take the pill (due to migraines and a sensitivity to too much estrogen), I was put on an anti depressant (which was to help with the mood swings), but wasn't implemented because of depression (I wasn't depressed), but to help with the chemical imbalances that I was experiencing due to that time of the month.

Let's keep talking about this, because there are months when it's just so hard to control my emotions just before it happens. And like you, my back hurts. I also gain weight and become bloated.
