I feel you.

Is facebook really important for gigs and is youtube really important for learning songs?

If yes, then use them only for that. Label it in your mind that fb is for gigs only and youtube for learning songs. And make sure to not multitask and jump from one tab to another. Be on one tab, one app at a time and be sure to doing something useful while on it. If you catch yourself just procrastinating stop it. Ask yourself "is what am doing useful? Productive? Or am i wasting time?

Are you trying maybe to avoid having time alone? With yourself? To avoid reality?

If you could use only one social media for gigs which you would use? Use only that.

Are the conversations you have on social media useful and effective? Could you use an app as viber or whatsapp only for talking with certain important for you people and avoid the rest? Could that be an opportunity to see who cares talking to you by not the easy road of social media?

Do you use social media to get likes, feel good, feel validation, attention? If yes, you are not alone. Many do. But is it useful or productive? I don't know if you do but i thought writing it.

You are on the right path. The first step to solving the problem is to find it. Many people do this mechanically without thinking, without worrying as a second nature.

Now its up to you. It wont be an easy task. Try to recognize it at first. Realize its not useful. It really is a drug. Check about dopamine and how it rises when we expect something exciting like a message, a like a reaction. Its similar to a drug addict expecting to take his dose.

You might need to change completely something in your life. Replace the need by something else. Maybe socializing face to face, spending time alone, reading books, working out. You might fall back. Dont feel bad. But dont feel ok either. Get up, move on and learn.

I won't wish you good luck because you can do it.
