Hero, I am sorry that you had to learn how tough life can be at such an early age.
You have a choice here.
You can cave into the pain and frustration that your enduring.
Or you can look beyond it and find hope.
If you allow those afflictions to limit you they will further control every aspect of your life. Negatively.
If you can find something to live for and be happy about, it will lessen the control that your conditions have placed on you.
Find support where ever you can and use it.
Do not endure this alone.
Get all the information that you can about these disorders and the treatments .
Arm yourself with this knowledge and LIVE your life to its fullest.
These disorders can limit your Physical abilities.
They can not limit your mind . Unless, you allow them to.
Good luck my young friend.
You are very brave to post about this and very wise to do so.
