You are lucky to have a partner who wants to help you out of your problems.See, he confided in you about his feelings & you appreciated it.You have always kept your issues to yourself,& are not used to vocalizing them--this too adds to depression.Believe me,sharing your worries & fears with a trusted confidante is also a kind of therapy.It helps to get the load off your mind.Besides your partner will be able to understand you better ,he has less chances of hurting you unintentionally.If you are able to get over this block you will feel much better.
