Hey there,
Welcome to the forum! You should make sure you keep posting here.. it helped me so much because i felt that nobody understood.. and the truth is nobody did .. or could.
Firstly if your parents are working and you are considered financially dependant on them because you cannot work. If you can prove your disability from a doctor you should be covered under one of your parents insurance. I know this because I once worked at a call centre for benefits medicar etc... talk to your parents, I am so sorry about your father. I know it is hard. But just remember-- he does not want to be the reason you are unhappy. Live for him.
I thought my life was over at one point and felt as though i was waiting to die. Don't listen to what others say, just do whatever you are capable of doing. that is it. I was a huge burden on others for along time.. lost my friends as well. But it took me two years to finally find a friend who is worth my love. It's a hard process huh
Do not be afraid to reach out and ask for help.
p.s. if you were injured at work, you should be able to press charges/get financial help if they did not train you the proper way to lift with your back. This is mandatory at hospitals. If they did not teach you this-- or you were forced to lift something you knew was too heavy you should contact that place of work and see what your options are.
Hope I helped at least a little.
Things will look up for you, keep praying and you will succeed. Believe in yourself, You WILL be ok, it's a learning process and once you've figured out how to set things straight your happiness will slowly come back to you.
Much love,
Robyn
