What keeps you going?

I have been battling severe depression and anxiety during and after the service and most of the time I get overwhelmed with it. Been struggling with finding a job as I can't do physical labor and the jobs that I seek (office, administration type) I get passed over for as I don't have sufficient experience to prove that I am a good candidate and ones that I can fit my school schedule in. Not trying to have a pity party but sometimes the battle seems very overwhelming. I will greatly appreciate the advice and words of encouragement
