I wondered if there was anything in Orthodoxy that speaks to depression. I struggle with mental health issues myself and my faith has been a great comfort to me over the years, but there have been elements of Christian thought that have been decidedly unhelpful - Christians should never be depressed and so forth. I am feeling familiar doldrums these past few days and wondered if Orthodox thought would tell me to pull myself together or if there was more to say on the matter.
I will pray for you. I myself frequently get scared and depressed. I suggest:
1. Do not feel ashamed. Much of the Bible was written with you in mind. All of it actually, when you think of it (Metrolitan Kallistos Ware, who is an auxillary bishop in your Green and Pleasant Land, and famous English convert to Orthodoxy, perhaps the most famous), wrote in The Orthodox Study Bible that the Scriptures can be read as a letter from Jesus Christ to us. And frequently, as the Psalms attest, we are depressed.
2. Talk to your priest. Both your Anglican priest and if you have an Orthodox parish you are inquiring into, your Orthodox priest also.
3. Talk to your doctor. The NHS is making a major push to help all people with depression, and there is no stigma or incovenience; if you actually have any kind of clinical depression there are a vast array of treatment options available at no cost on the NHS. And Orthodoxy embraces mental health; there are many famous Orthodox psychiatrists.
4. With the guidance of your priest, take up the Jesus Prayer. You don't have to go all put with a prayer rope or other accessories; I myself have these but primarily say the prayer mentally without their aid. It does help.
5. I mentioned the Psalms. You might enjoy reading them. Are you participating in the joint reading of the Psalms with Liza? If you don't want to commit to reading the whole Psalter, which you ight not want to do as it is formidable and you don't want to risk burdening yourself with any unwarranted feelings of regret, just read some Psalms recreationally and enjoy reading and praying the Psalter as long as you want.
6. There are a number of other enjoyable Orthodox spiritual texts and Biblical passages. The epistle to the Ephesians and the Gospel of John, the Hymns of St. Ephrem on Paradise, the Liturgy of the Hours, and so on. I particularly like the collection of wisdom in the Amusing Stories collected by Mar Dionysius Bar Salibi of my Church; he calls these "amusing" and some are funny, but others are taken from the sayings of the Desert Fathers, from Greek philosophers, from Iranian wisemen, Jewish sages and so on. It is quite a fun book. Two books in the Old Testament inspire me greatly: Ezekiel, who has a vision at a time when all hope is lost of a figure who to the Christian reader is clearly our Lord leading worship in a mystical Third Temple, reminiscent in shape of a Christian cathedral, and a vision of a field of dead bones being reassembled into living bodies in the Resurrection. I also really very much enjoy Nehemiah, with its account of the restoration of Judaic Orthodoxy by St. Nehemiah the Prophet and St. Ezra the Priest, who along with St. Zadok and St. Aaron is one of several high priests od the Old Testament who remind me of our blessed Orthodox bishops who have been glorified as saints over the years. These are just some works that appeal to me, find something that appeals to you.
7. Tomorrow is Sunday: pick up a copy of the Sunday Telegraph. even if you aren't a Tory, and look at the Animal Pictures of the Week. Or view them at telegraph.co.uk. Nothing like some cute animals to cheer you up and remind you of the beauty of God's creation.
For that matter, actively pursuing other recreational interests of yours can also help and is recommended. In the UK. there are a lot pf fun things to do even if one is down in the country, so do them. Lent is a joyous fast of purification and happiness in the Spring as we prepare to celebrate the Resurrection, so enjoy it, and enjoy the magnificent weather the UK is being blessed with at the moment.
