demande d'aide pr corriger 1 lettre de motivation en anglais

[White angel]

bonjour, je suis etudiante en medecine, je dois me rendre en stage cet été en Croatie. pour, ce faire je dois rédiger une rapide lettre de motivation en anglais, est ce que vous pourriez m'aider à corriger mes erreurs ? merci par avance pour votre aide !!!

",I'm a french student I’m 23 years old. Currently, I’m studying at the Medical school in fRANCE in 6th year.

Since my youger years, I was dreaming to be a doctor, so when I was eighteen, after my A level, I decided on leaving to the medicine school where I was first provided a theoretical instruction during 2 years. Then, I attended a mixed instruction for 4 years including hospital training on morning and classes on the afternoon. During my work experience in the different departments of the hospital (cardiology, vascular surgery, Gynecology/Obstetrics, Pediatrics, oncology, urology, neurology, orthopedics and emergency medicine) I could extend my clinical skills beyond my academic training and acquire valuable knowledge in medical practice.

I also had the opportunity to join a humanitarian association in Morocco which allows me to go there two times. The first mission was aimed at doing free surgery orthopedics on children affected by strephenopodia. The second one allows underprivileged Moroccan population with facial dysmporphy to undergo free surgery.

Quickly, my preferences went in surgical practices, especially in maxillo-facial surgery. During my hospital training I had the opportunity to work as an operating room assistant with a French maxillo facial surgeon who was doing plastic surgery. She has great skills and really loves her job. She really makes me want to practice in this specialized medical field later.
Moreover I like travelling a lot. I would like to come to Croatia because I have always been attracted by this country and I was never lucky to go there. Given that Croatia offers me the luck to gain work experience working in my favorite field, I would like to take this opportunity to discover this country in term of both medical field and cultural domain. I would also like to acquire a different point of view concerning from one hand another health system and in the other hand concerning medical studies.
Last, but not least, I think that given the current context of globalization, a foreign experience is an additional advantage in order to cultivate a good relationship both with patients and medical staff. I also think that it allows everyone to keep a certain degree of open- mindedness which is an essential part of the practice for my future job."

Bonjour
Partant du principe qu'une lettre de motivation doit refléter ton vrai niveau en anglais je ne corrigerai ici que quelques erreurs qui m'ont vraiment piqué les yeux

Étourderie : Since my youger years

I also had the opportunity to join a humanitarian association in Morocco which allows me to go there two times.
La fin de la phrase est au présent. Si tu es déjà partie 2 fois, elle doit être au passé. Si tu n'as pas encore fait ton deuxième voyage alors il faut l'expliquer plus clairement et en parler au futur.
(De plus two times = twice)

École de médecine se dit plutôt medical school.

Dans l'ensemble ça me semble pas mal.
