Angry so much

I'm typically the one that encourages other people. I'm usually the happy one, but lately I've been angry a lot of the time. I'm unemployed and have no money. I've applied for many jobs. I have masters degree. I'm fortunate to live with a bf who will help me out. But that makes me feel worse because I don't want to be a burden. I know I should count my blessings. But I'm just angry. I don't know what to do.
