I am glad you are going to therapy and Al-Anon PacApps. It sounds like you have a good handle on your emotions. It's important to also maintain your social life during this time, such as hanging out with the guys, playing basketball once a week, or whatever it is you enjoy.
I know this is difficult, to think it is the end of something, but just try to stay in the Present Moment, don't dwell too much on the past or worry too much about the future. Focus on today and taking the best possible care of yourself as you can. Be kind to yourself and recognize that you are learning new things, like a new language.
