Is it normal to want to quit intern year

I had my parent pass recently. I'm just so sick of everything. I'm broke from helping my mom out financially when my dad was sick. Drained my savings. I'm drained mentally. I just started floors. The med students present better than me. I feel like a retard because I can barely remember all the info on my pts let alone think about the medicine. I'm just fed up with everything rn. My finances suck, I feel dumb, and I hate working so many hours. Plus my mom relies on me for everything. Paying bills(just helping navigate not paying all the bills, she doesn't know how to use a computer), keeping track of her health stuff. Yesterday I just started crying because I was putting together a dresser and the parts were too heavy so I gave up(I live alone). I'm venting but I'm just so angry that this is my life. I'm also angry that I have no help. I either have to push through or find something else to do. I'd rather find something else.
