I'm very glad to hear that. It's normal that you go through these phases of feeling like just chucking it in.
As you get in to a new subject and become enthusiastic about it, you realise how much there is to know, how little you know, and everyone else seems to know so much more (which is not always the case, by the way). And you feel everyone else is talking a language that you don't understand - using words and phrases that don't make sense to you.
But it does begin to make sense. Even without you being aware of it, you find yourself understanding things that you didn't understand the week before; posting messages using words and phrases that you didn't know about only a few weeks ago.
So, you stick with it.
