Moody!

I'm extremely anxious yet stressed and also depressed. I am graduating this year and am super excited but I don't want to leave my boyfriend. Well be together for a year soon and we've been through a lot already. Sometimes I feel like he doesn't care if I'll go away but I know that's just me being the way I am. I have separation anxiety! It always seems like someone is leaving.  I'm depressed almost all the time it seems. I try to keep myself occupied but it just happens. Anyone know of a way to fix this? I 100% refuse to take medication for it.
