Suicidal thoughts and fear.

My wife went through bad life in her previous life. Now since we got married almost 1.5 years, she is having fear, depression, bad mood, anxiety as she left her two kids behind. Anyhow now since she was on medications and she came up from that. Begore 3 months she was very fine and with lots of weight gain. So she insisted to stop all medications and we stopped. Zhe was very fine till.now almost 3 months without any medicine. But suddon now she felt fear in day time and last night she had suicidal thoughts also asn now she wants to crack UPSC exam and wants to study. I am encouraging her but anyhow she is not able to remember things and getting frustrated. Last night i gave old med. Censpram lite/ stablon/Divaa. Now she is not ready to take that due to anxiety and weight gain. When she was not taking any medicine was not having any anxiety. Now started since i gave thus medicine. She is not ready to visit doctor also. Pls suggest. Earlier med. Tryptoner/censpram/amitone/divaa/stablon
