Is Hysterectomy The Only Way To Prevent Pregnancy?

Question: hi my n ask XXXXXX isXXXXX and I am 35 years old. I am considering getting a hysterectomy. My reason is I lost a daughter my first pregnancy she was 8 months old. About a year later I got pregnant again and after Reading a all the books and doing my first pregnancy buy what those books said to do, so when I got pregnant the second time I kinda gave up I didn't see the point it didn't work the first time. after struggling for a couple weeks the state did step in and I put her up for adoption and when I did that that's when I made the promise to myself. when I was 25 and had my second daughter I told myself 35 was the age if I hadn't had a child by 35 when I turn 35 it was to make the decision. I suffer from mental illness I suffer from bipolar disorder borderline personality disorder, PTSD, schizoaffective disorder, as well as panic and anxiety attacks with suicidal tendencies. These are things I have dealt more throughout the years and more so the last 10 years. And it's taken a toll on my state of mind I do not feel I am stable enough to raise another child or to get pregnant again. I do not think I could bear the pain anymore. So my question for you is with my mental illnesses would it be in my best interest to let it go and move on with my life and get the hysterectomy done. There are no symptoms I have the IUD implant for birth control now it's a 10 year one it would come out when I'm 40. And personally I'd rather be w out my organs than have to worry bout birth control. I just don't think I can do it as much as I would love to be a mother again myself. however I cannot bring a child into this life not knowing. when I'll have an outburst or breakdown I do at least once or twice a week now already I couldn't do that to a child. I think the best for me would be to just take the stress of the what if or should a's out of the picture this way I can move on
with my life and move forward. (Not married) however my boyfriend and I been together over six year. so that gives me four step children a step daughter and one step grandson also...so they help keep me content and ok with the decision I'm making... so I guess the other part of my question is are physicians willing to do that if there is no type of cancer or anything like that going on? Is mental illness and instability grounds enough that a doctor would perform a hysterectomy on me?
