Stuck...

I just don't know what to do........ this sucks! We're stuck in this small house not knowing what to do from here. We know we want to be out of this house but where to!? do we buy a bigger house or should we go ahead and put an offer on the land that I would like to be located at and build after saving up for a few years, but that does mean staying here til we can save up.. Alex seems to be about ready to lose his patience with this house... which is weird b/c he is only here half the time I'm here.. You'd think it'd be the other way around huh? Its been going ok so far in this house.. we do want more space.. I just need to get a shelf system for around the house to make it less stressful in here.. For example, this computer room, i have a big box of books in here waiting for SOMEONE to build me a bookcase... that someone is my hubby.. I asked for a bookcase for mothers day.. and we have like 6 totes of toys on floor that could use a shelf... Wall shelfs would be nice too for random stuff.. I'd love to have a room just for hobby stuff and computer room... I know how I want my future home to be built(picture above with a few changes to make, I'll have to hire my bro-in-law for that!) I'm just waiting for the right timing to come.. Sooo anyone with good advice? stay here and buy land and save or just move on to a bigger house? The perfect thing would be... move to a bigger house AND buy that land and save.. but thats not really possible right now.. What i was i even thinking in the first place to get a small house when i've always wanted 4 kids!?!?! STUPID!! Obviously i was in a hurry to move in our own house.. Now i'm sorry that I did that...... Hope someone learns a lesson from me!
