I recently went through a breakup and have felt the same feelings of being alone, no support network and no friends.
I also know the feeling of not being hired because of no work experience.
What I tell myself is that 'You're not alone'. Everything you're feeling I guarantee there is someone out there that feels the same way.
What's your favorite thing to do? Watch movies? Play games? There are a million of social groups online and offline you could join to meet new friends. I joined one at my university where we just watch anime and play games every friday.
Getting that first job is hard, however maybe possibly doing some volunteer work in the areas youre interested can help. I volunteered and taught english to an immigrant once a week and it has helped me out with employment.
I tell myself everyday, Don't give up hope. You are not alone and it helps me out.
So Izimini, youre not alone and dont give up hope mate
