I cry when i think about how happy i was when i was a kid and how miserable i am now..what can i do?

See a Psychiatrist: Many people feel miserable in their lives. It's not easy to juggle all of the demands of adulthood. But, if you are miserable to the point of crying it really may be helpful to get professional psychiatric help. A good psychiatrist can really help you work through those issues and give you the support you need. Best of luck.

See a professional: I think discussing your concerns with either a consellor, psychologist or psychiatrist would allow you to an alliance and assist with moods you are going through. A best friend, partner, clergy may also assist in this endeavor.
