Im tired of falling in love with random people almost weekly and then getting all heartbroken and delusional without the other person even knowing anything

Im tired of dolling myself up for work daily, putting lots of effort into my looks and clothes hoping we will have new fun coworkers but that doesn't happen since 2 years 

Im especially tired of people and YouTube videos telling me to start thinking positive and positive will come your way

Im tired of overthinking 

Im tired of wasting money on more clothes and makeup and things that were designed to give naive people like me the hope their life will change when they get that new product 


How does one completely detach themselves from such things? What do I need to do to just wake up in the morning, go to work and then home without any much thinking? I hope someone understands what I mean and can put it in better words or give me advice.. thanks
