Good points.
The OP described no less than 5 of the “warning signs of depression” found on any number of websites, those that my D has to check “yes or no” to every time she visits her pediatrician. These include OP’s feeling of hopelessness, loss of interest in the activities at her school, constant crying, constant exhaustion, and lack of energy. While it is on the OP to get help/move on/find solutions, the very nature of her feelings is that it will be hard for her to muster up the energy to DO them. She seems interested in getting help of some kind, and I hope she does.
Her issues may have nothing to do with being immature, but in being overwhelmed with an entirely new situation for which she was mentally blindsided through no fault of her own. Any kind of depression, whether it’s situational or not, can appear in a person who never saw it coming. It has nothing to do with how prepared or mature they are.
As difficult as losing that great scholarship would be for OP and her family, there are far worse things that could happen. Hopefully, the OP and other new freshman in her situation will never get to that point.
@WISdad23 I understood where you were coming from & appreciated your advice as well. I don’t think I’m actually in danger of letting my grades fall or losing my scholarship - I had some pretty rough times in high school too & managed not to let it affect my 4.0 - but it’s important to be reminded of what my practical concerns should be and 100% of my focus, externally, is on doing what I came here to do (excelling academically). Also it’s nice to hear that some struggling/weird transition period is a normal part of growing up and that it’s not just me.
Thanks @sseamom as well for empathizing with my mental health concerns. I’ve def long suspected that I have latent depression or something similar, and I think this massive change has just brought previously masked symptoms to the forefront. I’m sure the counseling, along with the other advice (exercise, getting involved, etc) will help but for now I just needed to hear that I’m not doomed to spend my entire life feeling crappy. I really appreciate everyone’s input 
That’s good to hear, OP. Even though it may not seem like it, knowing that it will get better can be a wonderful glimmer of light to follow. Best of luck to you.
Just wanted to post sort of a concluding update, in case anyone going through something similar finds this post and wants to know what my situation is now: it turned out that time really was all I needed, and I panicked for no reason. I’m doing great, I love college, I no longer miss home, etc. The main thing that helped was joining a few small, fun, tight-knit clubs that have given me a nice social network to rely on & something to do with most of my weeknights. Thanks everyone!
Great news and thanks for reporting back!
Thanks for the positive update. I hope this happens for my kid.
I haven’t read the entire thread so sorry if this has already been said, but go home! Its only 90 minutes away! Maybe every weekend if it makes you feel better.
If you read the last few posts, you would see that the OP is doing great now. No need for frequent trips home.
This is fantastic!!! Thanks for coming back and letting us know. I hope that you come back next year and look for the posts from similarly-suffering freshmen to give them some advice and encouragement!
Homesickness is normal and we all feel it. The tears dripping from my chin as I type this are evidence of that.
Hang in there @logcase18! I hope you’ll be able to visit home soon.
Thank you. I was able to go home for both Thanksgiving and Christmas.
