My German is getting worse and worse
I can't comprehend basic things anymore. I don't use Duolingo much anymore since I finished the tree a while back but I do use it from time to time and am stunned how much I don't know.
I have been studying for 20 months and can't understand simple dialogues and make simple mistakes. When you grow up only using one language, it haunts you for the rest of your life.
The moral of the story is that if you have children, make sure they grapple with multiple languages at a young age.
Well, if you don’t do something, your skills deteriorate. It happens for everything. If you constantly use your skills, they remain strong and natural.
For easy evidence look at any sports league. At the end of the season there is a break. They then return for practice so they can get up to the skill levels appropriate for the real games.
That's unfortunate. You should try practicing the language outside of Duolingo; Clozemaster is a good post-Duolingo app to use or even Memrise.
I feel you struggle, I have been learning for a similar amount of time, although less intensely. I would recommend the Duolingo Stories and also Deutsch Welle Learn German. You just have to want it and push for it. It will take me 5 years, but so be it, no way it is going to defeat me.
That's a totally normal phenomenon. I've forgotten much of the Japanese I learned in college (though not all!) And even my native Portuguese is rusty due to lack of everyday use. I can understand it just fine, but my brain works in English and sometimes has issues filling in the blanks in certain words.
Consume German media, try your hand at reading books, and keep studying outside of Duo.
Try listening to DW live every day for one hour, it will help a lot. Also podcasts music and youtube channels.

No its not that as with each language "actually learnt", it should make more easier to learn not harder. The issue is that you did not continue using what you learnt. My mother used to say to me a saying "use it or lose it"
and if you crammed and also rushed the tree and did not put things into your long term memory properly, what you learnt will drop out.
I notice you have focused on many languages, that may not have helped either. Some of us really have to get one ingrained at a time and are not as lucky as those who can learn many at once. The best thing to do is to focus on a language till you can comfortably use it and then make sure you listen to radio or watch movies in that language regularly.
This is normal. My degree is in German and I lived in Hamburg for a year and was once fluent. I have barely used the language since I graduated and my fluency has slipped. In fact it was getting to a point where I couldn't even have a basic conversation in the language. This is why I am doing Duolingo so I can hopefully unlock some vocab and grammar which is locked away in my brain somewhere. But I am also taking German books out of the library and finding German programmes on TV to watch. My next step is to find a German speaker who will hopefully meet me for regular chats. You need to absorb yourself as much as possible. If you're not losing it then you will start to lose it. Especially if you learnt it as an adult.
Just practice, sir! You can use practice and you'll remember your German.
if you play video games try to play with native speakers the help you out or read books and watch videos in German
My native language is Spanish, but I have a long time studying English. Maybe your problem is that you have not been constant or you only use Duolingo to study. You have to try to immerse yourself in the language. I have never been in an English-speaker country, but I use apps like Italki to find a language partner, I read almost everything in English, and I consume content in English that I truly enjoy. Of course, I still have grammar mistakes (I don't study grammar frequently); however, I understand everything, and I speak in a natural way. My best advice to you is to enjoy the process and practice at least a short amount of time daily :)
