I rarely turn to anyone but myself, as I am the "advice-giver" of my friends and I don't trust my family. If I write down my problems I can usually act like I'm giving someone else advice and that would help me, because I feel as though I am not made up of just one person.
A psychologist or counselor if it was really difficult. Sometimes they're nice to have as they aren't involved in any way and can give an objective view. My pastor would be someone I have gone to before. My husband is always there for me. And I have been blessed with friends who while I wouldn't completely lean on them, would at least make me feel like I wasn't completely alone.
