Can you help me please?

Hi everyone. I'm Esra from Turkey. I'm a clinical resarch coordinator. English is very important in this profession because all documents and data system programs are English, so I have to learn more English but I'm sick of grammar books. I need to try a new method. I cannot go abroad because of economic problems and conditions, so ı need your help. Actually, my knowledge of English is not very bad. I can understand and speak simple sentences, but this is not enough.
