I am so tired of myself. I keep crying and worrying that my boyfriend will leave me. He's a great guy and often reassures me but he has many female friends as well. I fear that I am not good enough for him. I feel helpless. I just become so obsessed with him sometimes and I can't help but keep stalking him sometimes and it adds to my anxiety. I try to keep myself off from stalking him but my thoughts are all on him all the time. What's wrong with me?
