Anxiety

My boyfriend leaves Thursday, the 15th, for Israel (we live in California) and he won't be back until the 27th. He's going with his mom and our church to see historical monuments etc. I'm super nervous about his plane ride and just him being out of country. From the 19th-23rd, I'll be gone with my students for camp keep and I just feel so overwhelmed. Is there anything I can do for this anxiety I'm feeling? I get anxiety a lot and have really bad separation anxiety, but can never seem to find a way to fix it. I just cry a lot, all the time
