Has happened to me a lot. I eventually ended up with a nice job, despite my stutter, and despite phone calls still being difficult. You gotta keep putting yourself out there. Some days will be more fluent than others, and you'll get lucky and have an interview on a good day. The worst thing you can do is get caught in the trap of thinking things will never improve. I'm a severely negative Nancy most of the time, so I get it. But if I could pull myself out of the bullcrap thinking and find a decent gig, I have no reason to believe you can't do the same. You got this.
