I dont know all your story and how bad your situation is but I am definitely sure that there is more to you than just being ill and someone will see past that for sure. It is just you believing in that and holding in there. Someone will love you for who you are as a person - not the illness. You would not say that to somebody who had any other illness - they wont love because I have x or y etc.
Physical or mental illness (it is just an illness not the person) and that is what the right person for you will see - you, the person.
So dont worry the time will come.
Warm wishes xx
