Well, the bigger question should be "do you need to date?". Sure, as ace, you might not be aromantic, but to be fair, I feel the thing you might want to do is to "let ot happen if it happens", rather than building up a stress from needing to find someone to date, as mostly the people seem to date in order to find a compatible match for sexual relief, rather than a deep relationship. And judging by the community, I guess that is not your aim.
None the less, if you feel your fear of social interactions is indering YOU in life, then that might require active work. One solution being drama classes, or as they call it in my native language "expression skill" classes. Also, you might do well to remember that people who are in to extreme sports put loads and loads of money to feel fear, and you could easily get the same experience by just socialising with people, so instead if letting fear hold you back, learn to enjoy it (that's what I did).
And for finding meaningful relationships, nothing is more effective than expressing your passions; if you're in to pottery for example, let it show, and other people interested about the subject are more likely to initiate converstations with you. Eventually statistics dictate that you will find people you like to be around with. As dreadfull as it sounds, you just got toput yourself out there.
Anything beyond that advice, I'd say people would need to know you more personally, as there is no set pattern of behaviour that would provide 100% sure results.
