My husband wants to divorce me. After 4 years of mirage.?

My husband Walked out one day and decided he wanted a divorce. Now that I've cried and lost 18 pounds because of depression. I realize that I need to take care of myself. I have tried to see a psychiatrist but I was only able to afford one session. I feel that I need to see her more often because I have now opened my eyes and realized that I was emotionally and mentally abused by him and his family. One month before our Mirage I he gaved me an STD. Which was very traumatic for me but I went ahead with the wedding. One week before the wedding his mother decided to throw him a bachelors party. Yes his mother! He didn't/ I didn't want him to go but his mother called me yelling at me that he had to go because she had already organized everything. Him and i talked about it and we agreed that he was going to attend and we were going to meet at my apartment after the party. He never showed up. I went looking to him at his moms house and thought the worst I never said anything disrespectful to her. Just demanded to know where he was at. She got upset and slapped me. I just walked away in tears and never spoke to her again. When my husband found out he chose to not speak to her either. He stayed away from her and his siblings. Throughout the time the younger brothers ages 20 and 17 would send me emails. Telling me that I took thir brother away from them and that they hope I die. That I'm a fat pig and they hate me. I cried everyone but my husband just told me not to pay attention to them. I feel that I mas mentally and emotionally abused.I put up with all this because I love him and for him to just walk out on me. Will I be able to make him pay for psychiatry sessions? Is there a way to get him to pay for my std medication since I will have that for the rest of my life?
