College, even a community college, is far different than high school. It is like two different worlds. Don't waste your time comparing the two experiences, I have gone to 4 colleges(2 CC and 2 universities in 2 different states) and have never seen roving bands of bullies or instructors that were cruel. It is just a much nicer environment. Sure, in many(not all) cases, the standards and amount of work are significantly higher but that is a good thing.

High school is in the past, leave it there and move forward.

Having mental issues does make things harder but talk to the equal opportunity office for available assistance and services. It is not just for hearing and sight impaired people. The offices at Eastern Washington University and Arizona State helped me greatly with my MH and neuro issues.

The Walla Walla area is fine as far as it goes, if you like small communities, but besides the community college and state prison there isn't a lot out there. Housing is surprisingly expensive there also, at least buying real estate. I was helping my sister look, no idea about rent. There are schools over in the nearby tri-cities and that area at least has a few more things going on since it is significantly larger but nowhere near a big city if that is what you are looking to avoid. If you haven't been there you should spend a weekend and see how it feels.

There are many schools in Washington that are better than WWCC, although as far as CC goes it is nice but so are the ones on the west side and the two in Spokane. I have only been in the area once so take all this with a grain of salt. I am not trying to put down the area, if I enjoyed smaller towns I think I would like it there.

CC's are a really good starting point for students like me that didn't have stellar high school grades and were a little intimidated by the whole thing.

If you are a 10 hour train ride away, you have to live out of state. I can't think of any point in the state that is that far of a drive, much less a train ride(Maybe the far NW part of the state on the peninsula is that far of a drive???).

Like most states, out of state tuition is really expensive. One of the great benefits of CC is that it is cheaper so you can kick the tires, so to speak, and take a variety of classes to figure out what you love without paying massive fees. That advantage disappears when you come from out of state. If you are coming from another state it will have a CC (several) at least as good as WWCC.
