Hey, don't sabotage yourself like that or create a self-fulfilling prophecy that carries on what sounds like has already been a lot of pain. Sometimes its true that having "baggage" makes us more than some people are willing or equipped to handle. There are people who have become toxic as a result of their past traumas but its not innate, its usually because they have chosen not to address the things they have gone through and have relied on maladaptive coping instead. That doesn't sound like you.

I actually have a lot of respect and feel that my life is enhanced by the friends and partners that have been through shit but actively coped and attempted to heal from that. I know that they will not always have it perfect, they will struggle sometimes, but that is human and we'll go through it together. Its kind of a shitty truth that some people are more work because their lives haven't been perfect, and its true that other people have the right to decide if that is something they feel up to handling. Its not going to damn you though.

Worry more about continuing to build the kind of life that you want to have and less about negative self talk about "bringing people down". You'll begin to attract the kinds of people you want in your life when you treat your life the way you want it to be lived. I've been dumped and cheated on for having too much baggage. My partner has been through the same thing. We both have worried about being alone forever because we are too fucked up for anyone to love. That is a pattern of thought rooted more in trauma than reality. My partner doesn't bring me down and we both work to lift ourselves and thus each other up. If we fall, the other waits. Just keep working on yourself and the rest will fall into place.
