Do you have regular access to the internet? If you do then I recommend possibly going on some type of online peer counseling site. Possibly something like IPrevail (https://www.iprevail.com) or 7Cups (https://www.7cups.com/depression-help-online/) where you can chat to people about your depression and it's kept confidential. They should both be free so you don't have to worry about money, you might need an email address but I think that's all. You might also want to read up on managing and possibly recovering from depression, as well at the causes of it.
Alternatively, depending on how good your relationship is with your parents or friends ,you can try talking to one of them. You don't seem to have the best relationship with your dad, so maybe try talking with your mom about how your feeling if you think she will support and help you. If you have any close friends (the kind you can have genuine conversations with and can keep your secrets), you can try talking to one of them.
I know how you feel, I've been depressed myself in the past and I've gotten better over time. I still feel a little depressed from time to time but overall it's not nearly as badly as it was before and usually I feel better if I talk to someone.
