Extremely sad

My boyfriend is not in prison but he is in jail for 7 months. It has been close to 30 days and I am having a extremely hard time dealing with this. I have never had to face anything like this in my life. He is my best friend, my soul mate and I get to see him once a week for 15 minutes through glass. Everybody says I need to just keep going in my life, to stay strong. But how are you to stay strong when the one you are closest to in the world is not there. I have a very conservative judge mental family that do not understand this but still are trying to be there for me. To be supportive. I keep thinking everyday will get better but it doesn't. I am the one out here dealing with the finances. Everything falls on my shoulders. So if anyone has any advice on how I can adapt better please let me know.
