So the other day was the full moon.
On the days leading up to it, I was aggressive, then depressed, then I wanted to be alone from everyone and stayed by myself.
On the full moon, I was aggressive to the point of near violence and had to be by myself to the point of immediately leaving when people were in the same room as me, and very restless.
On the days after (still now) I'm still very irratable, but now my whole body hurts, is exhausted, and i have -100 energy. Im not depressed that much, just drained.
Have you asked a doctor yet? I think it's always important to weed out any physical or mental health issues before looking at spiritual ones.
If you have had it professionally confirmed to not be physical or mental, it could be a spiritual issue.
You mentioned that you didn't want to be around people did being around people make it worse? Getting drained or emotionally overwhelmed around people can happen to empaths. If you think you might be an empath, you can put up spiritual shields to help you block out other people's energy. You can also work out things that help, such as taking time to unwind in your room after being around people.
Some things that might help if you are an empath:
Regularly put up shields to prevent people from affecting you too much
Make sure you've eaten enough and are well rested before going anywhere
Have a small snack and some water after getting back from a social event
Bring a water bottle with you if you need to be around a lot of people
Allow yourself alone time (don't isolate yourself just give yourself a healthy amount of time to unwind)
Avoid toxic or especially draining people
Set boundaries (if someone invites you to a huge party and it sounds really uncomfortable and exhausting, it's okay to say no. You could suggest hanging out with them one-on-one instead)
Ground yourself after a social event (I like a meditation technique that involves holding a smooth rock and imagining any energy hanging around that's bothering you going into the rock)
Carry protective talismans. If you use crystals, you could carry one to help (I'm not big on crystals so I can't provide many suggestions, but I've heard there are some that help)
If you notice that something like being touched or loud conversations make it worse, it's okay to say something. If you have a friend who hugs you all the time and it makes you tired or upset, it's okay to politely set boundaries. Explain it's not personal, but speak up if you need to
Also, empathy isn't always bad by any means. It can be incredibly overwhelming, but when people learn how to balance it out, it can be a very rewarding gift that allows one to understand many different opinions, know how best to help someone through a situation, and sometimes pick up on people who might not be good people to talk to. If you are an empath, it might be difficult to figure out how to manage your abilities, but don't be discouraged if you find out that that's what's happening.
If empathy doesn't sound like what's happening to you, feel free to disregard the above. It's just what I could think of and what I thought might help.
Ask anyone who works in an emergency room or is a first responder and they will tell you that people often act in crazy ways during a full moon. No one knows exactly why or has found a medical reason for it, but it does happen and is a well-known phenomenon.
