I think I found the 2. Look at the 7 again and slightly to the right of it. The background dots are colored slightly darker brown compared to the rest of the background. Trying to focus on these brown dots instead of the green 7, you can make out the slightly shifted 2.
Didn’t see it until many people here referred to a 2.
I don’t know where you live, but if you have these thoughts, please look for the various general helplines telephone numbers, where you can talk with people trying to help and support you and giving you access to a better life. It might not be easy to see for you right now, but it is out there.
