I agree with Gertie - it sounds odd but it is correct. You may improve the statement by adding "There" before each phrase: "THERE are twice as many people killed in country A as THERE are children born in country B." This helps tremendously with syntax and understanding. Hope this is helpful!

Because "recently" is a specific time marker, you would use simple past, just as you would with any other time marker. For example: Recently I read a book about turtles. I saw my brother recently. Yesterday I ran to the store. Last week I visited my mom. NOW, if someone asks you a question in the present perfect such as, "Have you seen your mother recently?" you may also answer in the present perfect: "Yes, I have seen her recently." But you may also answer "Yes, I saw her recently." and it conveys the same meaning. I hope this is helpful!

Both are grammatically correct and convey the same meaning. These would usually be spoken in a rhetorical sense to yourself. If you wanted to ask someone if they know where your keys are you would say, "Do you know where my keys are?" or "Do you know where I left my keys?" For example, if I am rushing out of the house and can't find my keys, I usually say to myself, "Where have I left my keys??" or "Where did I leave my keys?" as rhetorical questions. They are not meant to be answered by anyone - just a statement to myself to indicate to others that I have lost them and cannot find them. I hope this is helpful!

Both of your statements are correct. You may simplify your first statement further by saying, "We're not the same weight." This is not necessary though - just a suggestion.

Both of your sentences are correct. In the first you are using the infinitive (to take) and in your second you are using the gerund (taking pictures). Both have the same meaning and both are grammatically correct. You can use the gerund after the verb "love" as well as the infinitive in this context: I love to run. - infinitive I love running. - gerund I love to swim. - infinitive I love swimming. - gerund I hope this is helpful!

I don't expect this to completely resolve your question, but for me personally, I find that keeping a diary and writing about all of my anxieties and problems really helps me to calm down and better organize my thoughts. I usually write before bedtime so that my brain feels more relaxed and I can sleep better. Have you tried writing in a diary before?

I know this may sound strange, but I have found that walking while memorizing with flashcards helps me tremendously. I can easily learn about 20 words per hour. What I do is first record a new word on a voice recorder in the new language, pause for a few seconds, then say the translation in my native language, and repeat this for up to 20 different new words. I keep my flashcards with me in the same order as the words on my recording so I can check the word if I am unsure of the spelling. When I go for a walk outside, usually to a quiet park, and just listen to my own voice speaking the new words and the translations. It really helps me to memorize words and there have been some studies that have backed this up: https://digest.bps.org.uk/2010/06/23/memory-performance-boosted-while-walking/
