does life only get worse?

I’m 16 and the past 2 years of my life have been horrible. my grandma died in a car crash due to a seizure while driving and she was in the hospital bed while my own father watched his mum take her last breath. Already a great way to start the year, not even a few motnhs later my kitten I had just gotten was mauled to death infront of me. And to top it all off at the end of 2024 my family member (sibling) I was very very close with had committed suicide. ever since that point my life has been filled with misery and pain. I got jumped by two people while in school and they got a slap on the wrist and kicked out of the school. (I had also been bullied all my life in school having adhd only made this worse)

nothing on the level of that has been happening to me since my family members death but now I just feel empty. Nothing makes me feel truly happy or not depressed anymore and if it does the minute I’m alone I remember everything and an immediate unexplainable sense of dread washes over me. I don’t even think I’ve fully understood my sibling wont be coming back and anytime I try to rememebr my Brain just blocks it out it’s starting to feel like they never even existed.

I have another sibling I speak to all the time and we’ve grown very close since what had happened but even then there’s still things I don’t say. I also have many self doubts due to adhd and have a very weird thing about being liked. I feel Sometimes my friends don’t like me or if they do stuff without me I don’t feel included and it usually gets me really upset but I don’t say anything because I don’t wanna cause a scene but the more I don’t sya anything the more it eats me up it’s like a vicious cycle. In my friend group there’s a girl I like, I don’t think she likes me back and everytime I see her outside while I’m rotting in my room I feel jealousy or sadness or anger and I don’t know why. I also have my final exams in under a week and the pressure has been unbearable. So,

Will life get better? If not what the fuck do I do?
