YES!!!
there are alot of things that you can do that are Cost&Time-Effective that can help you out. some examples are:
-Healthy diet ((Eating 3 times a day at the least))
-Exercise regularly ((once a week at least))
-Pick a time where, every day, you can do something that relaxes you & use that time, every day, to do so
-Journaling, in a notebook or on ur computer, or even on scrap paper ((whatever suits you))
-Remembering to breathe... the "right way;" in through your nose & out through your mouth.
-Reminding yourself that, "you can do this," "you will be okay" ((what ever "this" is))

i hope this helps you a great deal, these are things i do myself to help maintain a managable level of "crazy" in my life (((lol)))
