Can someone tell me if this translation is accurate?

I am writing a letter to a mother of my friend in Turkiye. The first section is the English version and the second is the translated version. Can someone tell me if this is correct and any corrections that need to be made. I am concerned because my computer keyboard is not set to make the symbols used on certain letter...can anyone help me. Any help would be greatly appreaciated! Thank you soooo much!
Marcella

As far as I can tell, it's quite accurate. The only sentence that's a bit odd is, "Ben kendimi iyi hissediyorum," but I think that just sounds strange to me because I haven't heard it in a while. I would suggest placing the Turkish letters where they belong (s --> ş, c --> ç, i --> ı, g --> ğ, etc.), because that makes it much easier to read.
