If normal relationships don’t help at all, one place where manypeople find comfort and banish lonely feelings in in religion…developing a relationship with God. Depending on what you believe,you might want to try that as well.
Being married doesn’t automatically solve a problem of emotionalisolation. Even physical proximity can’t. Developing close, loving,consistent relationships is a good way to help with feelingisolated, but even if the marriage is perfect the feeling couldpersist. Maybe think about whether you are holding part of yourselfback from the people around you, or whether you feel like you can”be yourself.” If not, try to open up a little bit more toothers… they will usually do the same in return, and you mightfeel more connected.
