I'm sorry to hear that. There are some really bad moments from time to time. But I can say that with years of practicing in uncomfortable situations and gaining some confidence (generally by not caring what others think) it gets better. Also for dating and friends speaking and speaking in public is a very small part of it what's required to be a good friend/girlfriend. It is an obstacle, especially at introductions and getting closer to someone. But you can have qualities like being caring, having integrity, having skills and helping people... for which a lot of people would like to be close to you way more than to a person who does not stutter but lacks those qualities.
