I really don't handle being ghosted very well. Even if I know the person has a valid reason, they are bussy etc even if it's only temporary and sometimes when I'm overwhelmed I even do it myself so I also feel hypocritical when I get upset when someone temporarily ghostes me. But it just trigers all my insecureties and I can't even tell that to the person because they are not talking to me. 

Are there other ways to handle this than "just focus on yourself" because I really can't. I feel like all I can think about is this situation and I can't concentrate on anything else and it pains me. How do "normal" people handle this? Are there healthy ways to deal with this because I can't think of any.
