Fear of missing out & social media addiction

Does anyone else find it hard to focus on doing productive and long-term-reward activities, instead feeling the urge to browse social media and see people's faces all the time?

I wonder if this stems from me not socializing enough, and my brain freaking out about being separated from the tribe.

Unfortunately I don't know many people I identify with here in Lisbon, and most people have full time jobs and busy lives and don't have much time to hang out.
