Life gradually becoming worse

As I say this I say fuck it, 'cause there's no way I'm ever going to conquer life or anything in life if I don't do that. I feel like people often enter that bubble of safetiness and stop trying anymore. I also want to say pretty things when I'm feeling good, but wouldn't you know sometimes I hate my life. But life's been getting gradually worse... I am desperate for real advice... Like just tell me your daily routine, tell me everything you do from the moment you wake up, I mean not everything, but the important things, etc. Tell me how do you stay afloat in this life, especially after I'm about to become 28 years old. Tell me your secrets, I need to know... Please tell me how to enjoy life, I have hundreds of songs in my head and my brain is shit. I'm scared if this is how it's gonna stay, my fears have undergone me. Please give an extensive response, because goddamn. I thought maybe a feeling of sadness here and there wouldn't be so bad... Like I would eventually go back to feeling happy. Now it happens so rarely, it's almost like it happens in a heartbeat.
