I'm very sorry to hear about your situation and my heart goes out to you and your family. I will pray for your father's health, it is truly heartbreaking what is going on in your life right now. Although it seems dim, there are always going to be chance possibilities that things may become better, so even though hope is not there for you at the moment I hope you will be able to find it soon.
Have you considered getting help from a professional? If possible, see if you can schedule an appointment wit your family doctor and discuss seeing a psychiatrist. (they will diagnose you, and from there you should be able to see a counselor/therapist/etc.) Or if family doctor isn't an option do you think you'd be able to receive help from a school counselor? Since you are young it might be difficult to do these things without the help of your mother, but discussing this further with her seems important.
I don't want to seem like I'm meddling but as someone who has also suffered similarly I do think seeking help will benefit you. After getting diagnosed and starting a healing process I've improved a lot, and I hope you will be able to receive the same benefits.
Again, I'm so sorry for your circumstances and I hope you will be able to find peace.
There was a school counsellor that was going to help, but she disappeared because she was "sick". For MONTHS and never returned.
I don't know if she will return, I'll have to see in September.
Seems that I'm going to the hospital the day after I start school, for mental health. Since my mom thinks I am completely fine (that's what I'm like in front of family, happy and nice) she probably will make them care less about my situation but idk. She is already coping with so many situations in my family and doesn't have room for an "easily curable" one.
