As an english student I want to tell you this, we ( english language students) get bored / upset / disappointed when we realize that english is not as easy to learn as we thought, I know that because There are days in which I feel like that, It's frustrating when we feel stucked in addition we should be aware about something, there are a lot of non-serious students when it comes to learing a language, for your mental health, I think you should not pay attention to it
