I'm very sad to hear of your experience as I have had to endure similar problems with severe depression . I was diagnosed with the condition about 8 years ago and I have taken a variety of medications and tried many different therapies to address the problem. It is really important to remind yourself that the fact you suffer from depression doesn't discount the fact that God loves you. The love he shows towards those who have faith in Him is great, even more so when you have overcome challenges and taken strength from his word.
I have had to fight against post-traumatic stress since a terrible experience that I endured while living in Central America. Sometimes I have thought, quite wrongly, that God must not have any sympathy for me because I have sunk into despair and this seems wholly wrong, but if we trust in God's power and in the love of Jesus Christ as our Saviour we have the solution to any tribulation.
When life is difficult, we must remember that if God is for us, how much greater is He than any and all of the difficulties that we face?
