(post count is too low to post links, hehe)
I only came across this website the other day. It's quite fun, helpful, easy to understand, you can learn at your own pace and it's free. (i'm not being sponsored to post this! )
I read that taking up a hobby is very helpful to those who suffer from panic and anxiety so maybe this can help keep you occupied on doing something else.
