Life has a way of kicking you when you're down, I understand, i'm younger then you 32, but i feel I know where you're coming from, when i graduated from university i thought the employers would be climbing over themselves to get at me, boy was i in for a rude awakening, the employers didn't give a damn about that piece of paper a spent 3 years of my life working towards, the amount of rejections I got were shocking, some were even insulted me,
i too would go on to spend weeks where i wouldn't leave the house, looking back on it that's probably the worst thing i could have done, i put on weight and BOOM depression had snatched up another victim, family would pester me about not having a job, but god knows, i tried, eventually things got better, I landed jobs,i started exercising and lost the weight,
if i were to give you any advice it it would be, try to do as many positive things through out the day, it doesn't have to be big, it could be something as simple as making your bed, or vacuuming, or applying to some jobs, try going for a short walk, it'll clear your head, 45 isn't that old, you can do it if you set your mind to it
