I Am So Tired

I'm tired. I work hard, too hard, but it's a tough life. I'm a pharmacist and I often work nights, sometimes I work 3 shifts (two 8-hour shifts and one 12-hour night shift) within two days. I need sleep and relax, I need some time for myself, I need time to focus on my life, but I feel like I just work, sleep, work and sleep. Life is dripping through my fingers and I know it's my job's fault. I wish I could work less, get a job in a normal pharmacy that's not open 24/7, but I need the money. My boyfriend doesn't have a job and I doubt he'll find one anytime soon. We don't live together yet, but if we ever will, I think I'll have to support both of us. He's been through a lot in his life, struggled with depression for 12 years, he was hospitalized because of that multiple times and had a few psychotic episodes caused by a severe depression. He's okay now, working on his engineer degree, just got his driver's licence etc., but I doubt any employer would easily trust someone who has a 12-year-long blank space in his resume. I have to work hard to make sure we save some money for our future. It's okay, I don't mind working, but the tiredness is killing me.
