First thing first. Nothing and nobody is or should be more important than your own life and progress, unless you are in love, which is not the case. If you want care then first you must give care. Fill your loneliness with learning new things rather than alcohol which is only going to make things worse. Trust God and His plans and in your free time do some social service where you may possibly find some friends to share your journey.
Affectionately,
