Very fun trip Manda! You need to get another horse at some point.  You obviously love them, and have a passion for them. I wouldn't stress too much if you can't do it now though. I'm gathering your young. You have time, and the most important thing would be to take care of yourself, and set yourself up for long term success. That will enable you to be able to be able to care for the horse more easily whenever you do get one, less headaches and more time to spend enjoying him/her.
I'm not trying to be imposing with advice, just the opinion of an old man who understands.
