Sorry for the wall of text:

In the summer a lot of people go to festivals, others go camping, or stay at hotels, etc... But I don't really have friends anymore, so those things seem kinda weird to me. Why would I want to stay alone at a hotel and go to the pool alone, etc... that does not sound fun (I think...). "I go there and then I'm there, and that is fun. It is fun, right?", "Ok, I'm finished being here now I go 'be' somewhere else".

I like camping, going to the beach, I like music but I think the fun part of it always ends up being with other people. Make new friends who you can trust with similar interests and that's when you can actually have fun. How do you do that? No idea but I doubt being here will solve my problem.

So I know as much as you do. I'm gonna go for it, bring everything that I'll need to take care of myself, start in the wild maybe. Once I start feeling a little bit more relaxed and understand that I'm free to go anywhere I want and do whatever I want without caring what anyone may think about me, I'll start trying to meet people by moving closer to the city, beaches, hostels, couchsurfing, etc...

Here's an example: If I see some guys playing football on the beach, I'll ask them if I can play too. It's easier for me to decide if I trust them or not because I approached them, they did not approach me. If for some reason that goes wrong, which I doubt, I'll move to another beach or try with some other people, who cares... Maybe they'll be there again the next day, maybe we'll actually get along and I'll invite them to go to a bar, or maybe not, it doesn't hurt to try. The possibilities are endless, I guess I can call this an adventure... If I go to Spain I'll always have language as an excuse. ;) If I see some guy playing an instrument on the street I'll spike up a conversation with him, why not? Etc...

I made another post asking about where do I leave my backpack, maybe that'll help you too. I wouldn't want to go to a bar with it or leave it at the beach with no supervision.
