Lazy again

Even though I appear to be a hard-working person to other people, I am the laziest person in my family.

I am so stressed and freaked out, afraid that I might not be able to master my English or be indeed too stupid to do so.

I have done some volunteer work for the last seven days and it's now difficult to get back on track.

Any suggestions would be appreciated.

Just the fact that your English writing is so good should boost your self confidence. Get back on track!
