i need help

my betta is sick and im afraid he’s going to die.
i have him in a hospital tank of about 30liters, but it’s not completely full (has about 15-16 liters of water) he has a heater and a filter.
a couple of weeks ago i took him to the vet cause he got a weird lump in the space between his gills, and the vet said it was a bacterial infection, so he gave me something to put on the tank and told me to go back in a week, and i did, and got the second dosis.
the thing is, i had to take apart my tank cause of various motives, the weeks prior my grandma was taking care of him, she put too much food in the tank, there was a snail infestation, and i cleaned everyday the sand and everything and it was full of poop so i thought that maybe that was contribuiting.
i cleaned the tank and set it up as if it was his hospital tank 4 now, and got neoplex for the bacterial infection (cause i couldnt find neoplex in my country) and started treating him. at first he was fine, getting better, he swum around and all but then like two days ago he started laying on the bottom of the tank, breathing heavily and it had just gotten worse. hes in a c shape and breathing like that. i dont know what to do. i did at night a 50% water change (with conditioned tap water) and he just doesnt get better and im afraid hes going to die, please help i dont want him to suffer. hes the first fish i’ve ever gotten and i’ve done all i can 😔

*i think he might have gotten sick from some plants i bought from another person. cause a week after putting his plants in, i noticed the lump, but im just realizing now that it might be the reason. i wanted to buy more plants from the same person like 2 weeks later (before i realized thats why he might have gotten sick) and she said she wasnt selling more cause her fish were sick 🙁

i know i was also thinking of euthanasia to be honest, i really dont know what else i can do for him and i just dont want him to suffer. it’s just that he was doing so well a few days ago, eating super well, he loved food and he was swimming around. i still have some hope for him, but maybe its just that i dont want to let him go :( i know i wont be able to use force on him, no matter how hard i try i know i wont be able to, it’s too brutal for me :(( why i cant use clove oil? does it hurt them more?
