I think it is really hard to tell from this post, what is going on and how serious it might be. I just want to say that I personally know of three kids who were so dysfunctional from anxiety and/or depression at this point in senior year, and two did go to school and did fine, one took a gap year, went West for an outdoor leadership school, and went to college the next year. Our school nurse told me in the spring of senior year so many kids are a total mess. It is almost normal. One of mine appeared to be completely breaking down: she graduated three years ago and is fine.
This could just be typical senior year angst, and the weight of the transition out of home may have really hit her with that last visit. The reality of it. Many kids are very homesick the first semester even, and being close to home and visiting can really help. If this is what is going on, then assurances that she can come home and you will visit and so on might help. With my oldest, who has trouble with transitions, we visited repeatedly in the spring and summer before he went.
That said, there could be something going on that is more serious. I would not be quick to pathologize, but problems do arise at this age. Some are easily dealt with, and some are longer term and take some time. A therapist can certainly help. Sadness is different from depression. She might be feeling a let down of some sort, and the loss of an activity can have an effect. If she has less interest in what she usually is interested in, that may be of concern, but it might be part of the transition. Is there any chance of an eating disorder? I certainly cannot tell but you mentioned she is eating much which means the change is enough for you to notice.
Gap years can be helpful but they sometimes aren’t…it depends. Has she mentioned wanting to do one? (Frontier Nursing Service in KY needs couriers I believe, if that is of interest.) It’s fine to stay home and volunteer and work and so on, but her friends will have left, right? It can be lonely.
I think it might be jumping the gun. If this is just anxiety about the coming transition, and sadness about leaving home, and just plain fear of the new, she may be able to resolve it and head off this fall. A lot can happen in a few months. She can always decide to take a year off at some other time, or leave. It is true though, make sure her transcript doesn’t suffer too much.( If she is depressed or anxious, and it is documented, she will be eligible to register with the disabilities office and get support and accommodations.)
I had doubts about my youngest being ready. She spent a year at an LAC, left, did community college, and is now in an adult learner/degree completion program at a pretty good college while living with an old friend and working. Some kids have bumpier roads than others but end up pretty mature as a result. Whatever your daughter decides, things can work out!!
