A ton of it is mindset, remember that you need to get out there and rejection isn't always about you. As weird as it sounds, speed dating was one of the best ways to meet people for me. Do yourself a solid, skip the dating apps and find hobbies that involve people. Remember that while some people won't date you because of the stutter, some will be because they just don't feel a connection, not the preferred body type, differences in tastes, or a thousand other reasons. Remember that your stutter is one small part of you, what defines you is vastly more than it. It's nothing more than a cup of water in a pond.
