Well, usually I find that coming up with a good thesis is hard. Even with all of the information there for you to use, getting it into a thesis can be really tough. Also writing a conclusion can be quite tough. It's like restating everything you just said, but making it as concise and as meaningful as possible. That is a big challenge, for someone who loves to explain everything fully.
Another thing you might run into when drafting an essay is staying on topic. Many times it's easy to get distracted and start talking about something that has nothing to do with your topic. And being able to not do that takes a lot of discipline. So if this is a problem for you, everytime you write a sentence, ask yourself is that either on topic, or atleast supporting the topic directly. If not, then don't use it, or rephrase it.
Also, if you need help with just english stuff and writing and such, if you just message me, I'll be happy to help you figure out whatever you need to know. English and writing are tough sometimes. Especially when you're doing it at the mercy of whoever will be reading it. Let me know if I can help you. That's what I do.
