Feeling Defeated and Overwhelmed: Needing Reassurance and Advice

so this past month has been really hard alot going on , very stressed out, financial issues, health issues, car problems, just feeling completely defeated and beatin to the bottom ... 2 nights ago I lost my absolute mind it felt like .... I just felt the anger and the sadness build up inside of me .. I ended up smashing the visor in my car causing the glass in it to break and go everywhere , I bruised the side of my hand pretty badly from hitting things , I was screaming and crying at the top of my lungs sitting Infront of my best friends grave ... friends and boyfriend were out looking for me .... I'm absolutely ashamed in myself , embarrassed, feeling pretty down about the whole situation and myself.... it's 2 days later and my body feels rough .. I'm exhausted..I have no every , no motivation, I don't want to look anyone in the face , I can't sleep or eat .... has anyone had episodes like this and felt this way after ? I really just need some reassurance, some advice, thoughts , anything at this point 😞
