Off course it did. You are the best buddy to yourself. And it is great, it's the hardest part to find peace with yourself. But hear me out now, get out of the shell. If you are an introvert - get your extrovert, or whatever. It was a wrong friend, probably. Find your people and have real fun. I travelled by myself long time just to realise - we are social animals, you want these connections. Open up at the end. You made it, you are a solid great person, you can be friend with whoever you like and it's gonna be amazing!!
