Day 5 and im feeling like complete shit

I dont know why but since ive started nofap it has all just gotted worse. Today ive been feeling completely nervous without a reason the whole day and i just got mad about every single Little Thing. It just feels like i cant be calm for a second. These mood swings are also killing me. Like in the morning i felt kinda good then every hour it changed. It just went from good to bad and im just feeling like everything irritates me. I dont have urges to fap but im just feeling completely fucked up. I was outside for a walk and i felt kinda good but then i came back home and it got worse again. I dont know if its gonna be like this in the future but im hoping there is gonna be some change because im stressing myself for no reason and i think this could be because i dont get no dopamine anymore. Ive been fapping since i was 9. This is a really Young age to start but i never realized how bad it actually was. If anyone has any advice on how to be more calm i would be very thankful. However ive noticed ive been caring about myself more since ive started with nofap. Ive been going to Sleep early and been sleeping longer. Ive been Looking more on my appearance and been Eating more. I feel like im doing something good but it just feel really bad at the moment. I want to hear your opinion about this or Maybe someone experienced this Kind of Things already and can tell me something about it.
