(((((Lenighma))))))))))) I do not think you are a complete failure at all. I know that how it may feel to you. Your writing is wonderful. You express yourself great.
I have a feeling if you took a placement test you would see you would do very good. Not forsure as i am not a teacher

They would test you to see. There is hope. You may find you test above the kids in school.
you said (((I can't even focus on personal work, like my writing))) you did a great job with this as i said. Your spelling is way better than mine .
If you are having a hard time focusing have your Dr check for ADD? Just a thought as i am not a DR.
Please never be sorry here. Your post is wonderful.
I agree with ((farmergirl))) check your local school if you can and see what they can do.
