Help! i dont know what to do?

I have a very hard situation that is causing me a lot of pain and anguish. I don’t know what to do and I feel so lost right now. I am a 34 year old man that recently married his girlfriend after only dating for 3 months. We have been married for 2 months now, so we have been together for a total of 5 months. My wife is 25 years old so there is an age gap there. I agree that we did move way too fast and that everyone would tell us this. She is currently 3 months pregnant and the last two months have been pretty much a living nightmare. From the beginning of the relationship, this woman told me that she loved me with all her heart abnd that she had no doubt about the way she felt about me. We even talked about getting married soon. Two months into the relationship , she got pregnant after we had made a promise that we would wait until we got married to consummate our relationship. She did mention several times during the first two months that she did not want to get pregnant. But two weeks after we found out she was pregnant she promised me that she was ok with the pregnancy and she was even happy about it. I am a bipolar man that has did disorder for along time, but just recently came to the acceptance and realization that I am bipolar and now am seeking treatment (medication and therapy). From the beginning of the relationship she noticed that I had episodes of depression and mania and she would even think to herself that I might be bipolar. Three weeks after we find out she was pregnant, she was struck physically so bad that she had to leave work and unable to do anything physically throwing up all the time everything she would eat and nauseated all the time. I immediately started taking care of her like a good husband would and would only leave the house to go to work.. During the last 9 weeks that she has gotten worse and her mood swings (due to the pregnancy) have gotten worse and worse. During all this my bipolar episodes of depression and mania have increased and have acted out on those episodes with her many times throughout the pregnancy. Recently about three weeks ago she told me that she did not feel the same way anymore about me or about us and that the love she felt once for me in November through January was not there anymore. And when she explained that to me I thought that that explained the way she had been with me the last 5 weeks as far as cold, distant, abusive, and even made cruel comments. I have heard horror stories about pregnant women doing some crazy things to their husbands and even feeling like they do not love their husbands anymore as result of uncontrollable hormones, but these are marriages that have been together for years not 4 -5 months. I did also tell her that I was diagnosed with bipolar disorder and that started getting treatment for it. She stated that she always knew I had it so it came as no surprise. She mentioned that she was tired of everything and the way I have not been able to handle her hard pregnancy. I did explain to her that her pregnancy, and the way she has changed were triggers that triggered my episodes of depression and irritability but that it wasn’t who I really was and that I was getting help for my disorder but that she would need to be patient with me. I know that I have done everything possible to make her hard pregnancy better by taking care of every possible need that she might have though all this, but she feels that I have not done a good job of handling the pregnancy at all. So now I fear that because of my bipolar disorder I have tired yet another person out of my life. I try to be positive and think that its just her hormones talking or making her feel like this and making her the things she has said and not that she is realizing that she was only infatuated with me at the beginning and now because of what she realizes is wrong with me is not willing to deal with it. When she did tell me that she was no longer in love with me, I did tell her that I was leaving and I gathered all my belongings and left, while I walked downstairs she texted me telling me that I told her I would never leave her no matter what, I came back because of that , because no matter what I love her and I love that child she is going to have. I am so distressed and tired and scared that this woman who I fell in love with is now no longer in love with me, because I have pushed her away due to my episodes of this hated decease
