I have been diagnosed with mild depression and an anxiety disorder. I have been perscribed medicine, but it made me very ill so I refuse to take it. However I am plagued with thoughts that my girlfriend cheats on me and I check behind her on everything to find signs. She has done everything in her power to show me that she is not cheating and does not want to be with anyone else. However I become extremely jealous sometimes and do outrageous things to try and find her lying. If she does not answer her phone, I continue to call it. Sometimes I shake unrepeatedly and cannot stop crying, just because she is not answering her phone. This is destroying our relationship and I do not know how to make these unfounded thoughts disappear. She loves me more than anything and does EVERYTHING to show she is not cheating. If someone looks at her I am overcome with jealousy and rage. Please help me. Is this part of my anxiety disorder? What can I do to make these thoughts go away?
