Depression. For me. plz doc help me.

I love a boy since 5 years. We're in long distance relationship. I got married with him since last one year. V love each other deeply. But since last 6 months things were not going well. I didn't get that much back as I gave him whatever it is love, attention, care... I know he loves me too. But still our mindsets are so different. I became so possessive for him as time pass. On every 2nd or 3rd day we got fight. I think he never understand me. May b he think as same. I m an engineer. N I left my job to get marry him. Now I feel so lonely n alone. I have nothing to do. Negative thoughts r coming on my mind. Sometimes I think for suicide. I need him in each phase of my life but he never treat me well sometimes. V've very beautiful relationship in earlier times but now reality comes in front of my eyes. I dnt know what to do.Even I can't share this to my family. I need him I can't live without him. I need some help from him. But he is never there for me. Plz doc help me.
