I am going through the same thing but to a lesser degree. I don't know what this condition is called but I found, on the net, something that sounds similar to this. It's called Dependant personality disorder and It might beifit the poster or anyone to look it up on Google.com or I have a site that you can go to that describes the symptoms. WWW.psychcentral.com/disorders/sx13.htm
copy and paste it into your adress its a good site look around.
I would also like to say that Therapy does help!
Peace

Not that ur advice isn't supportive, but the gist I caught is a teen who's progressively isolating herself and has intrusive thoughts. Accessing counselling is pretty important, I think. If she has no one to talk to (and she doesn't confide in friends or family) then a counseller is an impartial, trained stranger who can help her to sort out her thought and cope with her stresses.
It sounds like maybe you didn't get the Love and attention while growing up that you deserved. Realize that sometimes this is not always possible. Some people are not capable of showing Love. I would recommend trying to get involved in activities that will make you feel good about yourself, either activities that you find healthy and fun or maybe something to help someone else out in need. This can be very gratifying. Concentrate on doing what makes you happy for now and then later you can focus on relationships with other boys/men depending on your age. Know that you are a loving person and have a lot to offer this world. Even though things may not have gone or are going the way you would like, you can decide to make things better for yourself from this point on. Besides anyone who cheats on you does not deserve your love, and you deserve better than that!
You will achieve significant benefit from speaking with a therapist. Tell your parents that you have some personal things you want to discuss with a therapist, and ask your parents to arrange this for you. If you can't bring yourself to say this directly to your parents, ask someone to intercede for you.
