Hi, Berries! Observations:

"Someone from my support group asked me out for coffee." Someone from your support group not only saw something attractive in you, that someone had the personality and/or courage to ask you out. How many others find something to attract them to you but do not (yet) have the courage to ask? The fact one person saw something in you they liked is an indicator there are others.

"...my social phobia kicked in." You had the courage to respond to the invitation despite knowing this could happen - brava! I wonder what may have triggered the social phobia: the person, the setting, the day, the time, other people in the scene, the weather, the coffee, sun glare, ambient sounds or noises, etc.?

"...I just plain did not feel like we “clicked”—nothing a lot in common and she told lots of stories where she failed or had been fired but always blamed someone else." Congratulations - you were focused enough to know you didn't click (at least at that time) and were paying attention to the point of being able to summarize what she said! And you did all that despite feeling uncomfortable - impressive!

"Am i just hopeless and destined to be alone?" Biased observer here - you're too caring and charming to be either "hopeless" or "destined to be alone." Trying to set aside my bias, I would say you have far too little data from which to draw such conclusions.
