I’m in a committed relationship and my bf and I see each other every week or so for a few days. He usually sleeps over at my place but sometimes I visit him. My issue is that whenever it’s time for one of us to leave, I get a huge wave of depression for the rest of the day/the following couple of days. We both work and we both have our own friends, but I can’t help feeling so utterly alone once he leaves. This also can happen when I’m done hanging out with a friend or something. I just don’t know how to deal with the depression and anxiety that comes with being alone after hanging out with someone.
