Don't know if this is exactly what your looking for, but I hope it helps: www(dot)duas.org/enemy(dot)htm
By the way, duas can be made in any language. God Almighty knows all languages.
P.S: Hope you get well, and I'm kinda sick as well, so I can relate.
I think the dua.org is a shia site. A more reliable site is

The Prophet (peace and blessings of Allaah be upon him) used to seek refuge with Allaah for himself, and the greatest means of seeking refuge that is available to the Muslim is reading the Book of Allaah, above all the Mi’wadhatayn (the last two Soorahs of the Qur’aan,
al-Falaq and al-Naas),
Soorat al-Faatihah and
Aayat al-Kursiy [al-Baqarah 2:255].
Among the saheeh du’aa’s for refuge that have been narrated from the Prophet (peace and blessings of Allaah be upon him) are:
“A’oodhu bi kalimaat Allaah al-taammaati min sharri maa khalaq (I seek refuge in the perfect words of Allaah from the evil of that which He has created).”
(Narrated by Muslim, al-Dhikr wa’l-Du’aa, 4881)
It was narrated that Ibn ‘Abbaas (may Allaah be pleased with them both) said: “The Prophet (peace and blessings of Allaah be upon him) used to seek refuge with Allaah for al-Hasan and al-Husayn. He said: ‘Your father [i.e., Ibraaheem] used to seek refuge with Allaah for Ismaa’eel and Ishaaq with these words:
A’oodhu bi kalimaat Allaah al-taammah min kulli shaytaanin wa haammah wa min kulli ‘aynin laammah (I seek refuge in the perfect words of Allaah, from every devil and every poisonous reptile, and from every bad eye).’”(Narrated by al-Bukhaari, Ahaadeeth al-Anbiyaa’, 3120).
It was narrated from Abu Sa’eed that Jibreel came to the Prophet (peace and blessings of Allaah be upon him) and said: “O Muhammad, are you ill?” He said, “Yes.” He said,
“Bismillaahi arqeeka min kulli shay’in yu’dheeka, min sharri kulli nafsin aw ‘aynin haasid Allaahu yashfeek, bismillaahi arqeek (In the name of Allaah I perform ruqyah for you, from everything that is harming you, from the evil of every soul or envious eye may Allaah heal you, in the name of Allaah I perform ruqyah for you).” (Narrated by Muslim, al-Salaam, 4056)
Inshalah recite the above 3x after each salah, in the morning and evening. May Allah protect you from the evil of His creation and bless you with shifaa and fast recovery. Ameen.
