Suicidal thoughts..

Not writing this post to seek attention. Just some help. I give up with life and feel I can't take no more. The only thoughts I am having now is to kill myself somehow. Maybe take tablets or something that will do the job. I'm a mother to a 7month old girl who has reflux from the day she has been born. She always has refused to take her bottle. About 10-15 minutes of fussing she will finally drink her bottle. I have suffered since the day she has been born. I have almost developed anger in me and harm myself because I don't have it in me to harm her. I would punch myself in the face and would hit my head on the wall. She cries all the time during feedings even in a public place she just won't feed. I have spoken to various different doctors and they all give the same medicine which doesn't work. My marriage is shit. I have been married for 1year now. All my husband does is argue with me over dumb things. I feel trapped in this marriage. He won't let me have any type of freedom. I just am lost right now. I don't have anyone I could talk too! I don't want to stress my mum out by telling her. I just feel sad and depressed. Can't stop crying because even my husband doesn't give a shit about me.
