I think my pattern of relationships is to move from one person to the next and narrowly and intensely focus on one person at a time that I think I use for emotional connection, emotional support, company, and way to feel like a real person who is stable instead of a lonely emotional wreck. But it seems I do damage to the other person, I feel like a leech in a way, seems that I drain the other person of their time and resources and when the relationship becomes strained enough I either drop them and move onto someone else or they drop me and I relapse into an emotional wreck again until I find a replacement. I've noticed this pattern for years now since my teenage years, I'm mentally dependent on others but I'm like a parasite to them. My friendships and relationships are very episodic and they tend not to end well, I think I put so much investment into one person at a time that I miss the larger picture about what healthy relationships or friendships are supposed to be like.
I've mentioned this pattern to my doctor and she sort of suggested it was a personality issue, so I read more about BPD thinking it would be related. Do other people here feel it is related or have these same patterns with other people?
