Addictions of all kinds do a lot of damage to the human being in its entirety. So does tech alcoholism. Your mind, your thinking, your heart, your feelings, your willpower, your body, all of them are affected in numerous negative ways. When you’ve reached the point where you realize you just can’t control yourself and do things that you don’t want to do, the damage you’ve incurred is already quite serious. At both psychological and physical levels.

There are 2 ways to get out of the chains and break the cycle:

• Humbleness as a spiritual attitude toward yourself and the world. You need to recognize the state in which you are, you need to recognize that it is your own mistakes and deficiencies that brought you there, and you need to recognize that you need outside help. Humbleness in practice means, for instance, seeking out help in those wiser than you, asking others when you have questions, doubts, not relying too much on your own opinions and ideas.
• Programmatic effort to tame the impulses of your body, to enable the mind to become purer and regain control of itself, to increase your willpower. Examples of this are fasting, physical work, sports to some extent, prayer and meditation, assisting religious service, occasional refraining from sleep, etc.

A lot of these ideas can be found in a more developed form in the Philokalia, a collection of texts about spiritual warfare and how to grow spiritually. A good intro to Philokalia: https://www.youtube.com/watch?v=lR-lI425KqE
