Hi DM. Firstly, welcome to the forum. Were all understanding people here so please come on here and chat to us if and when you feel you need to.
To me all attention seeking is is to do with low self worth and so you go out and seek it in being validated by men and action. I have known people, including myself, who have used attention seeking to fill a void inside oneself.
Do you go to see a therapist? It will definitely do you good to speak to someone about it and explain the whole course of how you've gone from energetic to drained. It could be a lot of things going on there.
It's good though that you are facing how you feel. A lot of people don't do that and continue on habits that arn't good for them emotionally. But (and I know it's hard) don't feel over guilty for what you do. You're human. You have needs and it sounds like, perhaps, you're needs arn't being met the way you need them to be.
I know what it feels like to feel very insecure about yourself and feel like your the last person on earth people would think about. One swoop of a magical wand and I wish it would go away for you because it's a pervasive thought.
If you go to therapy, talk to your therapist about all this.
It will be a journey to get back to how you were, but during the journey you will find out a lot more valuable attributes about yourself and slowly change for the better.
I guess it might help to remember that perfection doesn't really exist. Lets say you reach perfection, what next? We always want more, and should stop and think about what we have. It's hard of course, when we live in a world that spells out perfection in ads and media. The perfect look. The perfect career. The perfect way of behaving. The perfect house and children. The perfect style of life.
Keep strong DM. ((hugs))) You'll be okay.
