I take it you're in contact with physicians that are tracking your condition and its development, and you're not just relying on your judgement about your own mental state? If not, please get in contact with specialists ASAP, do not rely just on HN for medical advice.
Apart from the above, the best I could do is tell you to try to not be too hard on yourself. I know this sounds strange, but try to acknowledge the situation and that those are the symptoms. Work on accepting this as normal, so that it does not stress you out and lead to acceleration of the condition. If necessary find a person to talk to to help you deal with this, and to help you find what life changes to make so that it gets easier for you.
Just hold on. The science is catching up, and eventually it will! Stay strong, and do not give up!
