I just wrote a very long story in answer to your question, and read it back. I decided to pare it down to this, which is still a bit long. Sorry:
My wife and I suffer many problems and my wife especially, has severe disabilities. Her depression was profound for over 6 years. In and out of hospitals and the like. A couple of years ago through much prompting from God, that I will likely write a book about one of these days, I was called to the Church, and began the blessed road to conversion. My wife, (an atheist most of her life), began attending Mass with me, and long story short began RCIA with me after much loving pestering. From about mid way through RCIA you could notice a big difference in her. We were starting to be able to talk more and more. We developed a prayer life. We attended Mass, and really listened deeply to the liturgy of the Word, and the homilies. She was converting!! I was thrilled. By the time we celebrated our sacraments of initiation at the Easter vigil last year, she was no longer on ANY medications for depression, nor seeing any doctors for it either. She takes like 3 meds for her physical disabilities, which she now believes to be blessings. She believes herself to be healed, and I don’t doubt she IS. We have both become involved in parish lay ministry, and attend Mass regularly. The Eucharist and prayer is the central focus in both our lives. So what is the point here? We were both sad and desperately struggling people. We hated our lives, and the misery spread to everyone around us. We’re now very happy, outgoing people. It is BECAUSE of Christianity and the conversion of the heart, not in spite of it. Yes…Christians CAN be truly happy! We’re still embroiled in desperate financial problems, and we listen to the same news programs you listen to, but it’s all okay. We have faith that God will sort it all out, and furthermore point us towards the positive actions that we should take to help make things a little better in the world through giving us ministries. I don’t know if this helps you at all, but my biggest advice for anyone dismayed or overwhelmed by the world is to get more and more involved with helping others. Either through your church, or some charitible group. Take as much of your sulking time as possible and re-route it into getting out of self. Go to your Church and let them know your talents, (everybody has some), and see if they match up with something they need done. I’ll bet they do. This takes away the feeling of helplessness, and gives you a sense of community and love for your brothers and sisters you may never of thought possible. Fully involved Christians are the happiest folks in the world. You sound as if you’re without direction on your vocation. I’ll pray for you to find your happiness.
