Any advice would be really appreciated

I'm not attending uni cause I've been avoiding my groupmates in thesis. I shit scared of them of the confrontation. I've been so stressed it hurts me physically. I know it's my fault cause I can't really do what the assign me to do properly, I'm really REALLY TRYING. but circumstances just keeps fuckin me up, I'm broke my laptop broke I'm literally dumb, my brain is also broke. I'm so slow but extremely perfectionist. I start things then think it's not enough or it's wrong all in all then yeah I will not finished sht. I tried reaching out to them like, hey can you help me in this cause I don't really know how to do it, but they don't help me at all then all they do is gang up on me when they needed it. I know it's my fault.

It really hurts I wanna fucking die
