On struggling with learning Arabic.
You probably are giving too much focus on the grammar -- verb forms in Arabic, and not enough on the communication part. Which is making the learning process boring and not motivating you much and you feel like you can't do it, lagging a lot.
It's not your problem, it's the problem of the method you are being taught Arabic.
If you find you are twisting too much in فعل يفعل تفعل then drop that course. Find the one that teaches you spoken, reading, writing a lot more than what you are getting in your current course.
Even if you memorize all the verb forms it doesn't mean you can speak or read better than those who haven't memorized it all. Rather practice the spoken, reading, comprehension and vocabulary part a lot, and grammar will come on its way.
