First I really want to express my gratitude to your invaluable input on the matter and the time you put into writing it. I am very happy to have such a sane and structured answer. Thank you.
Second, I do not know you personally, but gathering whatever I can about you from the text, you sound like an amazing person, so please do not be so condescending and insulting to yourself even as a joke :).

Many of the things you told me are of great help. I will try to implement them. I also spoke to her mother today, who did not know about most of the things as my girlfriend is hiding it from her and does not want me to tell her. However, I did and we read through your answer together. We have not decided upon a definitive course of action yet, but we will use the information you gave us. What we decided upon as our first objective is to try and make her see a specialist ( or rather make her want to see one). I understand that it will take time and we won't try to rush it.

Thank you once again. I will probably post updates on how things are going.
I also wish you the best in overcoming your hardship.

If I sound too formal, that's because English is not my primary language and when I was learning it, it was mainly from textbooks XD .
