Lost my brother 2 weeks back

Using a throwaway account idk why

I 29m don't want to go into how just know that it was a freak unclucky accident. Post accident we scrambled for ccu bed which will got after 2 hours in which he was on ventilator but 5 hours post the accident we lost him. No miracles that day. Just completed the 13 days rituals a few days ago. We did the Chita, held his bones(Asti) in my hands, and also did the visarjan of Asti on Ganga. Still I just can't seem to process that he is gone. He (my twin ) was the brightest, most generous person I knew and he was my rock. Puri family ka shaan tha wo. Hamsha sabki help Karna. Fir hi kyun god/bhagwan aesa karte hain (agar wo hain to) 6-7 months back i got sick (stomach issues) and so I spent around 3-4 months on my diet and exercise. I got into a puja as well( 15 min daily ) and some so why why does shit like this happened. Shaadi ka mausam chal raha and ghar pe shraad hua. People saying you have to move on.. Be strong for you family.. Forget him etc.. How the hell can I forget someone with whome I shared my first breath?? How can people give advice like that! A minute I'm normal and then it again the realisation hits me he is not here. Every breath I take, every bit of food I eat he will not be doing it. Grief, anger, hopelessness, panic , the vanity of it all comes in waves in cycles or sometimes all at once. People say it will get better with time but here is getting worse. Like a bad dream which won't end. Right now I have trouble even looking at his picture. To be clear I'm not suicidal but it’s like I can't look at the future without him being there. I just can't seem to get back up. Just feel so weak so alone rn He was the best person I knew so. Every thing he took on he reached the top of the competition so why a cruel joke like this happed to him How have people here handled things like this?

Edit: thanks for the support I’ll try to reply once I can compose myself It’s just he completed the hardest part of his life Graduated from IITB and was almost done with studying abroad I just can’t just can’t ..
