Ive had 4 drinks of whiskey (40.5%abv) under an hour and i dont feel the euphoria should i need to be drinking more?

I know i haven’t had that much but most of the time it takes more to get me drunk than it used to. It mostly makes me tired , sometimes it will make me giggly. I mean, when I’m with my friends it’s easier, therefore i can end up more drunk compared to when im by myself. I mean thats a universal experience right? But recently when i went to a party it was more of a “i want to sleep” type of drunk. When i drink alone It takes way longer to feel happy and only on rare occasions i feel truly euphoric. Right now i am craving for that euphoria i had truly felt that one particular time. I don’t know if that sounds bad but i cant stop fantasising about feeling that way and that good feeling i had experienced. I also would like to know if anyone is able to tell me how long it would normally take for an 18 year old female of a a thin/average build to feel any positive effects of alcohol kick in at the current rate i am going. My tell tale signs that alcohol has affected me is that of a numbness on my nose and mouth and slowed breathing, or a brief feeling of warmth; does anyone relate to this feeling? But another concern is that when i had gotten drunk at a party, and instead of making me happy, i had a panic attack and felt like i couldn’t breathe? For the past three years i have been experiencing many health issues, on and off shortness of breath and tremors being one of them. It seems that shortness of breath can appear when i am drunk, also i can shake for a short time, i know it is a respiratory depressant but it seems to affect me more than it does for my friends. Even after i had a couple sips earlier today i needed to have a bowel movement and my insides were kind of burning, which hasn’t really happened that bad before, i know its a digestif but wtf.. I don’t know what to do. I just feel so tired right now but I’m not happy, what would you recommend i do, do i need to drink more to achieve that happiness ? Or should i do Something else…
