Want to learn and be friends?

I am Lolo, a 22 years old girl, and I want to learn English and make friends with people from other countries.

I've made the first line into a question but adding "I" to the start would also make sense.

I've put "a 22 year old girl" in between commas so that it flows better as one sentence and also because it is 'extra' information, the sentence would work just as well if the phrase wasn't in it at all!
