Hi, please stay strong. I believe in you. The trials you're facing right now will only make you stronger in the long run, you just need to hang on in there, and fight. The call center job can be blessing in disguise because you'll be forced to speak with wide variety of people, and many stutters have benefitted from having a customer-facing job. I know it's hard not to compare yourself against others, esp your twin brother, but you gotta focus on yourself. Everything else is noise and distraction. You can DM me if you want to talk to someone.
