How stupid I am!

Today I have spanish class in the afternoon. Actually, I enjoy studying but  I think that I'm not good at spanish at all.I have learnt it for 3 years yet I can't use it very well in all skills. I've tried to practise it but I could do that for a short while. Afterwards, I gave up and that's why I am not able to communicate with each other by using Spanish. How stupid I am!
