Good third-party apps.

I'm a nerd about translation, translation choices, and differences in cultures. I find it fascinating that the tiniest details in your language choice are capable of changing the meaning entirely. I also happen to be a Russian, so maybe this example for the Russian-English language pair would be interesting to you:

Given: комната = room мальчик = boy одна из = a (one of) эта/этот = the (that) в = in вошел = walked

В одну из комнат вошел мальчик. A boy walked in a room.

Этот мальчик вошел в эту комнату. The boy walked in the room.

В эту комнату вошел мальчик. A boy walked in the room.

Этот мальчик вошел в одну из комнат. The boy walked in a room.

English uses a/the to define what's known/unknown, and Russian doesn't have a similar tool but it can change word order and add some extra words for more precision. Russian also uses a lot of cases to define who does what and when, and English just doesn't need that, the word order does it all.

Looking at all that makes me feel like I'm watching something beautiful. Like I find solace in the fact that there is more than one way to see things.

People have already offered you some good advice and I just want to send hugs and love from a fellow Mordorian.

I think before you start something, you may want to balance your mental state first. Not improving but balancing it would be a good start. I know that would be hard without proper medication and care, but still.

What worked for me was having several days or even weeks off Internet, social media, and being as far away from other people as possible. To avoid drama (you might know what I'm talking about), I would invent some reason to stay alone that wouldn't raise suspicions in them like having to study or help a friend with some project. Then I would try to focus entirely on my body not thoughts, maybe take a walk or listen to fav bands in a way when you let music replace your thoughts so that it becomes your thoughts.

Actually, this resembles all that meditation shit, and sometimes it helps. Your goal is a detached attitude that you can use to make plans without having to consider any unnecessary feelings.

Once again, you're not alone, I love you, and more people around are open to love than you think.

Not really, that extra letter is a noun case, it serves grammar only. I guess the word all (всем) is what helps distinguish between the meanings here. It belongs to the semantic field of mir as in the world, while Russians don't use it together with mir as in peace.

That would be мир во всем мире, literally peace in all the world
