Kathy, you're welcome! I am glad to be here for you.
It is very hard to put your trust into someone then have them leave. It feels like a betrayal. And working through that can be difficult. His leaving just occurred, so this feels very intense to you right now. In time, you will be able to learn to trust again. It may not seem so now, when you are hurting so badly. But you will. It takes some work, some time to mourn your loss, and recovering. But you will get there.
There was a time that you managed without your boyfriend and you will again. Sometimes if you keep that in mind, it can help. And you do have supports. You have your therapist, I am here for you, and you have friends and family. Until you feel better, rely on everyone around you. They will understand.
Has your therapist diagnosed you yet regarding the stealing issue? If not, it is called kleptomania, which is stealing items that you do not need. It is a disorder that is thought to be caused by a lack of serotonin in the brain, so medications can help. Therapy is also one of the best options for treatment. It helps you address why you feel the need for the thrill of stealing and how you can work to reduce that need. You can also join support groups to share how others have been affected and to get some ideas on how to stop the impulse to steal.
Talk with you soon,
