Internet addiction

I have phone addiction and due toh this it's messing up my studies , frm corona(2020) life has been upside down ..

And i haven't been back on track since!

My mind just jumps frm one to another , either its manga, webseries , anime , yt ... a new addiction every time i think its over..

And i haven't been able to focus aon studies and procrastinating..its hard for me to leave internet either as I'm doing online classes

Please suggest me a way , all this just contributing to my anxiety and phobia...

And its been getting downhill now a days!
