Welcome to our group.
After reading through your post, I'm going to guess that this is your first year of college, second semester (is that the case?). I remember that time of life, and there's a lot to get used to all at one time. It's a tough adjustment when it all sinks in, and sometimes it takes a while after the initial excitement and 'newness' of it all. Maybe that's why you feel like being alone more now than you did in the first semester.....the pendulum is swinging a bit the other way. It also sounds like it's taking a while to find people who have similar interests, and that can be frustrating, too. All of this takes time, and it does get lonely when you feel like you're spending time with others 'just because', and doing things you wouldn't normally want to do just because you were invited.
Have you looked into any groups on your campus, or even in the vicinity of your college and suburb, to see if there are things going on that you would enjoy? I realize it's late in the semester now, but maybe there's something there for you that you could do in the fall when school starts up again.
It sounds like your interest in dirt bikes and motocross is still strong, and that's a good thing. Even when interest is waning in other areas, if you have a pet project or activity that holds your focus, you can still get some enjoyment out of life and feel motivated about
something. I'm also glad to see that you're into 4-H. That's such a great thing! Will you be active in that this summer?
Please don't give up hope on keeping some of the activities you love. Perhaps you'll have an opportunity to work somewhere that has access to the countryside, where you can spend time in nature and around animals, and ride your dirt bike.
Also, try not to worry too much about
what other people think, and whether or not you're fitting in according to their standards......we're all unique individuals, and have our own strengths and talents. I don't really think you've lost all your confidence, especially since you still feel confident when you're riding. I suspect that being in a new environment with people who have different interests is bringing you down, and that's to be expected for a while, until you find your own niche.
If you're still feeling concerned, and find that this dissatisfaction with life continues to affect your studies, then maybe you should talk to a counselor at school or your family doc, as Jamie has suggested. It can't hurt, and it might help you to move forward with things more easily and feel a bit more optimistic about
your future options.
Let us know what you decide, and know that we're here for you. I wish you the very best, Honda, and I hope you'll come back and post again.
