The person suggesting dating should be ignored. Don't just get a partner purely because you're bored because a relationship is serious work and commitment.
If you're simply bored and don't really want to die then I suggest you research all 3 sciences- Physics, Chemistry and Biology; I suggest pretending you're at high school and study these three like you'd study them back in HS, so watch videos of HS sciences like freesciencelessons and downloading science textbooks from libgen or something. Reddit is also helpful for recommending textbooks to use to study science which you can download on libgen. When you're confident in your basic science knowledge move onto college level sciences.
I also would recommend learning programming, specifically python and the C family language (C, C++, C#). The youtuber EJmedia has great videos on how to learn them.
Lastly, I would recommend exercising and eating a goodish diet that's 80% plant 20% meat, if possible do the 5/2/3 workout program and eat atleast 0.8g of protein per lb of bodyweight. Despite Reddit being a toxic cesspool, the subreddit r/fitness has good advice.
