I still follow your thread after all this time. Congrats on doing well in school and having a plan!
I'm glad you've still been riding all this time and have been working on your skill set. It's very admirable! I've been riding less and less these days, but Rusty has been my little miracle and has proved to the world that after breaking his lateral malleolus, he isn't done being a riding horse. I think everything happens for a reason, and I'm betting your next horse will be an entirely new adventure!
As for the friend thing, you aren't alone in that matter. Even in college, it can still be the same way. I've noticed that bigger groups garner this problem more frequently, where if you're quieter or more polite in your case and don't invite yourself, you tend to get left out. I guess there's fewer and fewer people out there concerned about others' feelings - and probably because you are kind, it's hard knowing you put forth such an effort and no one reciprocates.
If it helps you any in knowing you're not alone, my best friends are making lots of other friends, and while it's great that they are, they always want to invite their other friends along on our adventures, and then it always seems like I get left out.
I just realized this is a long, random novel that may or may not make any sense, but I'm glad life is going along mostly well for you.
