How do I cope with anxiety & depression

I don't knew how to feel about myself..😭 
For the past few months there are many things happening to me.. 
1. My parents are probably getting a divorce & my father wants to move to another state. My sisters and I have already told him that if he will be happy then we will be happy.. The problem is my father has epilepsy & for the few years has been suicidal. He lost his job a few years ago because he was in the hospital do to his suicid attempt & my mother didn't call everyday he didn't go to work. So his job used it as an excuse to terminate him.😭 
2. I was 4 months into the promotion I got at work.. When my father asked if I could come and help translate for him at his doctors visits and just keep him company. I told him to hold on and that as soon as I could get off work I would be able to spend some time wth him. By the time it was month 6 he really needed me since he had many doctors appointments.. He had also been wanting me to keep him company for a while and since he's depressed and feeling lonely. (My mom goes to work & my sisters and I are no longer living at home. Also my mother and father are not nice to one another) I was also feeling pressure and stress from my new position because of how the management was treating us. I couldn't sleep, I didn't eat as much and my fiancé said you don't even smile any more.. I when to the doctor and was prescribed medicine for depression and anxiety😭
My fiancé said to me one day you know what I know you are feeling that way because of work and also your parents. So he suggested I quit.. I thought about it for the rest of months 6 and did resign. To keep my father company and help him.. 
A month had almost passed when I saw an ad for  3 month classes on environmental studies.. So I enrolled because I want to better myself.. The coordinators also said they would help us find work afterwards.. 
I feel tremendously sad because I left my job and also about my parents situation.. I don't want my father to move away..😭 One of my sisters moved back to help so I could come back home to my fiancé.. He sees me cry and says I told you I would agree with anything you need to do for yourself.. To which I replied Thank You, you are my rock.. My fiancé said I had helped him when he needed it the most.. The thing is that I'm a woman who not only likes to earn her own money but also I more then happy to contribute in the household.. Since I feel that I'm not bringing any money to the house I feel horrible..😭😭😭
Like I said once before I have no idea how to feel about myself..😞😰😔 even thought the coordinators from the class said they would us help find a job.. I still feel like I'm never going to find a job.. I just don't know😟
To make matters worst I get more anxiety & feel depressed during my period... 😓😢😥😪
How do I cope with anxiety & depression without the medicine (I only took it for a few days & I didn't feel like myself also because I don't want to become dependent on medicine)
