Parents forcing me to get married and threatening me to kill if I said no to them

Sir I'm a doctor when I was in my internship I fell in love with a guy his name is rahul. After completing my internship I returned to my home in Trichy my parents want me to put a clinic near by my house I said ok with that everything goes well for 4 to 5 months. After that my mom saw me when I was in a call with rahul, things are getting worse day by day they asked me to get married but I said no and I confessed to them I'm in love that guy. But they not even asked me who he is they said no, I cried a lot and I'm in depression because I'm so worried about my career coz my clinic is not yet developed I hardly get any money from it and also I'm worried about my love life. My father spoke to me regarding rahul separately without mom in my clinic, he asked me to broke up with him, I said no dad u literally don't know anything about him how could u say no, he said then ok tell me about him, i said the truth about rahul he's Malayali and 11 months Younger than me, he is unemployed that time after these three things he decided and said broke up with him immediately. I said no dad just spoke to him pls. Then he said ok call him, I called him, he spoke with him and say you are so young and unemployed u will get a better girl in future and please leave her. He said actually we are waiting for your permission sir so I will wait for her. But my dad said to me our relatives won't agree for this so u have to broke up with him. I take these things seriously, I decreased to spend time with rahul like calls and chats infront of my parents. I call rahul when I'm in clinic only. Days passed I can't continue to run my clinic because I had a lot of stress and mental pressure regarding my patients flow. My father and mother always used to manipulate me with their words like we have to close the clinic, we are the one who spend money for ur education and clinic but u didn't obey our rules like that. I was in a constant mental pressure initially and had my weight gain almost 10 kgs and I had my pcos issues also. I really hoped someday things will change. But not, it will worse day by day, they are suspicious of my activities although I'm not in touch with rahul. Rahul understand me and the situation and he gets his job in Bangalore. And my parents without my willingness wanted to see the groom and asked me to give a photo of myself I said no to them. Suddenly they are very nice to me and get me whatever I want but I said no to them when they talk about my marriage. They really know I love rahul but they forced me to get married someone. I closed my clinic also because of stress and now I'm in depression and anxiety. They now constantly threatening me to kill me. Im scared now.i don't know what to do, please help me with legal services and I also need some money to be independently separate from them. They drained all my money earnings also. Im sacred they will poison me or do anything. Please don't call me they may see that also,pls msg me in whatsapp
