How to deal with being a Pisces?

I feel like a lot of my problems are with people, even my career-related issues. I think a lot of people with a more typical Pisces nature appear to others as someone they can run over or treat like crap and get away with it, in relationships and otherwise. I go through a lot to stay away from people, to be honest, because of it. They're too draining. I'm to that point where I'm just done with people's bs. I won't even date anymore. There has been this Scorpio I was interested in--very intrigued and attracted--and I went back and forth on whether or not I want to pursue that so much (i.e. just didn't take any action, didn't let her know I was interested, etc) that I think she's done with me now. Pretty sure it's for the best, because it would have turned out like all the other relationships and I definitely felt like she was the type of person who would steamroll me in a relationship if I allowed it and then move right along. The last relationship did a lot of damage to me, which is mainly why I won't date anymore and really was hesitant to try anything with the Scorpio.

Luckily for me, I have a lot of fire in my chart, and it has made me start going off on people as an adult. They're usually really shocked and it's really hard for me to do it, but 95% of the time it gets me what I want. I'm talking about even with bosses. I have gone off on at least two bosses (I don't care anything about getting fired, especially since I hate working anyway, so I always feel like if I do for standing up for myself then I just do). I think if I ever do date again, I'm going to act more like a fire sign about it, too, and stop being so romantic and emotional. Women steamroll romantics and then run off.
