Translation of claustrophobic in Spanish

Yes, as usual, if you don't see me on messenger just drop me an email. And yes, your sentence is almost perfect, but I would like you to refer to it as lower end... so maybe there are similar words to 'enrichment' and also you could use the negative form.
My mother tongue is Spanish. For one year I lived in Spain. I'm from Huston, Texas, USA, originally. I want to study Spanish literature next year. I have already been to my professor to discuss it.
Thanks again for your letter. For now, the weather here is like it is in your country, ice cold. I will write you a letter in Spanish and in English. So you can compare the sentences.
