What is going on??

I’m 23 and I have been drinking heavily since 2020 I quit alcohol in 2022, and my days this year were not that great I didn’t miss a day without drinking at least 1 bottle a day (by 1 bottle I mean 1liter of spirits) and when I took a break it was only for one day until I go to the shop and get another bottle I came to the point that I started to stop enjoying it, I didn’t know back then that I was using alcohol to solve my problem I went through this loop of regret and self-hatred in those years, anyways I’m good now I don’t drink like I used to. But there is this thing that bothers me and it’s the personality change, I used to be a different person before it, I think my brain worked differently, I used to think critically and take thoughts before doing anything or taking any action but now I’m not, I never take that many thoughts before doing anything, I used to take care of things there was this spark in life when something new happens, now I don’t give a fuck about anything whatever happens happens, when something bad happens around me I don’t give enough reaction, not panicking is great I know, but sometimes I treat these problems like they are not a problem and in reality it’s a disaster, I don’t what is going on with me but I don’t like this, I don’t know how to fix this, but I don’t like what is going on with me I losing this spark and trying to fill with anything, sometimes I do things I don’t do just to feel like I’m normal again, there is something is broken, life did that and I hate it, I’m not sad at the moment neither happy, I just feel gray and I hate this feeling I want back my reactions my spark…
