I'm sorry, but doing this typically just scares people off. Even if they do seem accepting, they are still judging. Don't hate yourself though; you need and want desperately to be understood, which is something I can definitely sympathize with. It isn't something that you can easily control because what it points at is more going on that is very difficult to control. I've scared away people too by being too open or "touchy-feely" or "creeper" or whatever they decide to call being emotionally open (I also feel like it is 10 times easier because I am male).
The best you can do at this point is send the person a message where you apologize for being so open and ask if they still want to speak to you.
As for the deteriorated healthiness, the issue really is what your relationship to fear is going to be. You, like me, are a person who is highly emotionally sensitive, which results in a high degree of fear. Don't kid yourself, whatever your insecurities, it all boils down to fear or the desire for things not to happen, and the fact that you felt the need to disclose this to someone leads me to believe that, if you don't mind me saying openly (and please correct me if I am wrong), your fear is largely a result of and directed toward your interactions with others and your ability to trust them. Of course, this is a fairly general statement and applies widely (meaning I didn't say much in saying it).
I don't that think you a broken. The issue is not that you are deficient; the issue is that your relationships are deficient. It is hard to know who to trust and when to trust, and yet the deep need for intimacy constantly goes unfulfilled. I don't have a solution for this other than to encourage you to pursue things that will allow you to deal with the fear in a constructive way; i.e. meditation and reading (and I'll recommend some books if you would like).
I feel though like I might be completely off in writing all this, so please disregard if I am.
Also, based on my experience with ENTPs, assuming the person was an ENTP, they probably thought "Wow, I feel really bad for this person, but I can't handle all their problems." and the reason I say that is unless ENTPs go the more existential route, they tend to feel guilty and responsible for other's emotional states- and what I mean by this is that they tend to feel that if they are to give advice to someone, they are somehow responsible for that person's emotional states. If this person was ENTP, they probably felt like they wouldn't be able to handle being responsible for your emotional states, so to get them back, you need to reassure them that you can handle them on your own and that they are not responsible and bare no burden for your emotional state (which they will still feel anyway probably, but it might make them comfortable enough to talk to you again).
There is one other very important factor: did you have a crush on this person?
