It all depends on you brother.if you really like English , I advise you then to not hesitate and choose it as the first option
as for the matter of difficulty or easiness, again it all depends on you..i Believe nothing is easy in this life ...it only by working hard and doing our best we can make things easy for us .
In case you choose English as your career, I advise you, as sis zineb proposed, to get prepared for your first year in university coz the mothod of teaching is gonna be different from that of high school and especially you're from somehow an unrelated branch
anyway, if you wanna help, we're here
I hope I helped
