Personally, I ended up changed my plans all together because of my faith. I intended to do philosophy but now will attend BU's school of theology. This is huge change to make from an arts and science program because there no secularized.
While I wouldn't expect people to completly change their plans like that, there are some things that can help:
1.most school have some sort of club or group that brings students of a particular faith together.
2. church, mosque's etc usually surround universities, large and small. Some are even on campus. Try to work/study a little less and visit once in a while or manage your time differently to allow for prayer and reflection.
3. Speak with clergy (phone, skype) ask for advice from former mentors, pastors and such. They can be a big relief at times like this.
4. Lastly, while being in a building with people of the same faith is a big deal, it isn't what religion is really about. Its about a personal experience. I've been true to my faith (I hope) without attending church for periods of time, and while it made it that much harder, I've grown because of it.
