Help! What if I don’t get into uni?

I am applying for postgraduate teaching. I didn’t get in last year due to my undergrate course workload at the time. I took a year out for a tonne of experience but because I wanted it badly I totally messed my interviews up! I decided I want to work for child mental health services and go to college night school to do tesol qualification . But I’m getting no support at home as my parents were like time to give up. I’m just so sad and down about it. All I do is cry. Can anyone give me advice on how to cope with not getting in again?
