Just wrote you a big message to have it all disappear. That's terrible news for someone with dyslexia!
What I wanted to say was hang in there! You are on this site and asking questions. Having the passion to make it better is half the battle.
I'm a professional cook as well. What has help me has been working on the computer. I taught myself to type by coping recipes out of magazines on an old type writer. I'm way older than you and now I do everything on the computer in Word because I have spell check and grammar check. Get a good computer and write it off on your taxes. You need it for your work. Start a file of recipes and cooking techniques you would like to try. We are creative. Write it down. Use the spell check and the dictionary. Sometimes I don't even know what a word starts with! Use the thesaurus (had to check that three times) if you are looking for a word. Dig dip. I try to look at it as a game. Some words I will never get right and have to use the spell check. But some time it clicks.
I never got a degree because I couldn't write when I graduated from HS. I flunked second grade and they just keep passing me along. They didn't know what to do with me like they know now. Get help. Talk to your local junior college. If you don't want to do the whole college thing take extension courses through the UC system. How about a pickling class or organic gardening course. That fits right in with what you do.
Most important DO NOT EVER FEEL ASHAMED. We are doers. We make things happen. You will become a major problem solver if you choose to not let this keep you down. Go for it with all you've got.
