Dear Madam Srimathi Devinarayan
Since you titled this thread "Marriage", presumably it is your marriage that is in trouble. You ask for a "good astrologer" to look into your (present) horoscope and advice you regarding a good path to your karma. Someone has kindly offered to recast your horoscope.
As you are in deep depression, what you need is probably not another astrologer, but a kind and sympathetic ear into which you can pour all your troubles in confidence. You need a mature woman experienced in the ways of the world who can see what is the best way forward for you to return to normalcy, regain your self-confidence, and face life with renewed energy and strength. Perhaps this confidante can also have a word with your husband who, after all, is the anchor of your married life. She can even talk to your children if they are party to your present woes. Or whoever is contributing to your present discouraged situation.
Let me assure you that I am not "dissing" horoscopes by any means. They have their (limited) uses, but are NOT always absolutely supervening factors in your life. Frankly, they can occasionally be wrong, no matter how meticulously crafted, and by whom.
Since you are spiritually inclined, why not reinstate worship of your kula-deivam?
There are numerous sthrothrams to Devi in her many manifestations. (The rhythmic and evocative "ayigiri nandini nanditha-mohini....." is one.) Choose one and repeat the naama or verse. You can do this silently, moving only your lips, or not doing even that. If you wish, light a lamp and/or oothupaththi before a picture or "mark" or symbol of the deity.
Go back to thoughts of pleasant things that happened before in your life, and in the lives of people precious to you. Your loving parents, your siblings, your grandparents, your friends in younger days, your elders whom you admired, your "heroes" and "heroines". Your school and college days, your early marriage days, birth of your children, your achievements, your possessions, anything that lifts your depression.
(If you wish, I can perform a "sudarshana-chakra pooja" and send the prasaadams to you. That might help. Let me know your gothram, nakshathram, and postal address. (I have done this, even for friends in Canada. And they tell me they have benefitted.)
