Ever heard the old expression that "no Jew is an island," or something like that? An essential "survival technique" for any religious Jew is to be part of an observant community. If you live in the dorms, this presents a problem. It would be much better if you could board with an observant family. It's very likely that such opportunities exist in Montreal; if at all possible, this should be your first step.
Secondly, you need steady Torah study as part of your daily life. It's essential to set aside some time every day and night to study Torah, preferably with a chavruta study-partner.
