Firstly i agree with bpt that you should check with the professional that you are working with, to ensure that you are stable enough to take such a drastic step (marriage). As for the other issue of wondering whether you will find him, thats something that just about everyone in the shidduchim world struggles with, and it comes back to the strength of your emuna and bitachon.
maybe read up on some crazy hashgocho protis dating stories to help bolster yours. Not trying to change the topic of the thread here but heres a good story to start you off. I know a guy who was older about 25 and he was sort of done with dating girls fresh out of seminary for any number of reasons. So at that point in time he had two girls redt, one was 22 with a job and seemingly older more mature and the other was 19 and fresh out of seminary. so he decided to go out with the 22 year old the logical choice who was a 4 hour drive away. bikitzur two days before he was going to drive there he broke his leg and the other girl (19 year old one) happened to be in town . . . now they are happily married. point of the story is when its supposed to happen it will happen with the right person. people get wrong information forget to call certain ppl etc etc there are so many stories out there.
good luck
