I dont know if this will help but if you go to the Citizen advice centre or even contact them via e.mail. And explain your financial situation they may be able to give you advice and also if your partner is unable to work as a British citizen he may be able to get to get unemployment benefit or income support if he is unable to work due to him being depressed. I also take St Jon wort. I was prescribed it by the Homeopathic Hospital and my dr gives it to me on Prescription. Its helps with my depression well I feel less down but its still overwelms me sometimes.
