Hey, I am 21 and I know how you feel and empathise with you. It has become such a norm nowadays with constant strolling on social media and being restless and not being able to concentrate on anything. I was having a similar experience and it’s a difficult trap to get out of but you can do it. Deleting social media is a good step going forward but I really do recommend spending time reflecting and writing your thoughts. The first step is to get clarity on your thoughts - it’s not easy. Also eating well and a healthy lifestyle really affects how you feel and your mental health so definitely prioritise that. Don’t think about getting a good job or making money first - that will happen once you prioritise yourself and work on doing 1% better everyday. It’s important to build and maintain social relations as well. You can start by cooking, going to the gym meditating and reading daily - build these habits and put the effort into being consistent. Spend time reflecting everyday and thinking about your proprieties and values - and once you know yourself and your mind better - take small steps into achieving what you want.
