In life there will always be changes. Sometimes it will be unexpected and others you have to be ready for. Always leave on good grounds with everyone as much as you can. You never know somewhere or another you may run into them at some point or another. Be willing to help the people who you are temporarily breaking away from at this time. You want others who you have had a relationship with for years to have good things to say about you no matter if you are in front of them or not. Take the time to understand where others are coming from. When others feel you understand them, they are more open to being welcoming. Also know there are better opportunities in other places in due time. Be patient and continuously put in the work.
