Hi StaticGhost,
Thanks for sharing your story with us. I am wondering how you feel towards your family? Do yo feel like they love and care for you? Do you remember feeling anxious with your family if they went out somewhere and left you home alone?
Have you thought about talking to a Dr regarding how you feel, they may be able to recommend a few suggestions, check to see if you do have depression and anxiety and offer ways to get through it.
You could Google "Separation Anxiety" and see if some ideas come up as to how you can feel more relaxed and calm when it comes to your relationship.
It is wonderful to love someone as much as yo do with your boyfriend, I don't think it is that healthy tough if it affects yo so much when yo are not together.
Hope you can find ways to be calm and enjoy your life too when yo are not with him.
Cheers from Dools
