I used to self isolate myself too , just smoke weed and hit the dab pens living in my own world because it was so much easier just to have fun on my own and not let anyone in. I realized when it came time to actually speak with people I wouldnt know how to keep a conversation , it gotten so bad that I had to literally ask my family how do I keep a conversation going or am I doing good which would fuck up the vibe . I would hate myself for not being able to speak clearly or fluently where I gotten so depressed and lonely , I was so alone , didn’t feel like my life mattered , couldn’t tell jokes because if I did I would stutter and fuck Ik the joke, speak to girls or know how to communicate with family which is so important. I had to realize weed and not speaking and being afraid was holding me back , I had to “kill myself” everyday to be reborn as a better version as me so I started going to the gym , I started to look better, speaking better , challenging myself everyday so I can speak to girls , make new friends at the gym , and honestly I can say my life is so much better from that dark place and I can help motivate others to be the best version of themselves LONG STORY SHORT : hit the gym, meditate , and have goals you want to hit and be the person you want to become
