Feeling unprepared

So this my 2nd baby... He is a boy just like my first and I have 12 weeks to go! I have all the big things. Crib,car seat,stroller, etc. But I have 3 outfits! We have been so busy remodeling and then dealing with Christmas that it has just snuck up on me! And we don't have the extra money yo be buying a ton of things with remodeling and replacing the motor in our car ): I feel so stressed. My mom is planning a baby shower for me but it will be cutting it close lol... I may try and hit up some second hand stores and see if I can fond some cute clothes that are in good shape. We didn't keep any of my sons baby clothes because we were so cramped we had no where to store them! We also have to buy my 3 year old a bed because he is still using the crib. ( turned into toddler bed) ahh feeling stressed!
