What to do?

I feel like I'm having a withdrawal. I uninstalled my Tiktok and online game apps because I'm hyperfixated with those things that my screen time averages to 9 hours per day since last day of May. i feel my brain is toasting everyday cos once I open my eyes and before i go to sleep, im always on my phone and it starting to cos me severe headaches and muscle pain. I'm already anemic and the lack of physical activity and sunlight for months would literally kill me in my sleep.

I thought the right solution is to delete the apps that I was fixated on but I'm still getting headaches but now I'm in the verge to throwing up.
