I feel ya with the whole space invaders thing. It sucks and I wish nobody would have to go through that shit.

The thing about testosterone is that it will make you lose some of your feminine features that you're not dysphoric over. Your body fat will redistribute to your belly, your chest will atrophy, you'll grow a lot more body and facial hair, get a deeper voice, as well as many, many other things. You can't choose which effects you get from testosterone. It also in many cases increases your LDL cholesterol and puts you at higher risk of cardiovascular health issues. It doesn't matter how low of a dose you go on, you'll get those changes after a while. If those sound like something you'd be okay with, then testosterone is a potentially good option for controlling PMS and all that. It can make mood swings and anger issues worse in some people, it's highly variable on the individual.

If that doesn't sound like a good option, I highly recommend trying birth control medication to treat PMS. It helps stabilize those hormones like T does, but you don't have the risks or changes to deal with. Also, it's a good option for when you're just starting on T and want some stability while going through second puberty. Gives the added benefit of no periods faster.

I actually had a horrible initial reaction to taking birth control. The one I was prescribed was an estradiol based one. I got prescribed it to treat PMDD while I was waiting for all my labs to clear me to take T. I got heavily depressed for the first two weeks, and I knew it was because of the medication. I kept taking it and eventually as my body adapted to it those symptoms gradually disappeared. From what I've heard, how it works is it ends up replacing the natural sex hormones in your body, doesn't increase them. Your body will decrease its natural hormone production in response to it. I thought I was gonna get super feminine looking and get even more dysphoria on it, but that's not how it works. There are also many different types of hormonal birth control that you can take to treat it, so some of it is trial and error.
