I am so torn here..

Hey ladies.. I know I am probably going to be ripped apart by some of you and thats okay.. I live with my past life choices every day still. I am gonna start by saying.. I have a ton of mixed emotions with what is going on. I came here because I know someone will read this and know what to say. Some will judge and some will help I am okay with that tho. As I need some advice. Soooo.. I am just over 11 weeks pregnant.. I am very excited about this baby.. I want to share it with the World that I am expecting. Here is where it gets a little harder. I have a 12 year old daughter. She will be 13 on November 1st.. When I had her I was 23. I was in a bad place in my life.. I was in active addiction. Now I did abstain from drugs and alcohol from the day I found out.. until she was about 11 months old.. When I stopped breastfeeding. At that time everyone around me was in their addictions. They were all using and it was only getting worse.. So fast forward a couple years. When my daughter was just about to turn 4 I went to my second treatment program.. It seemed to give me the tools I needed to stay sober.. For the most part.. While I was away at treatment tho.. Her paternal grandmother decided she was going to do whatever it took to make sure I would not get my daughter back. She made me a promise that no matter what it took I would not have my daughter back.. She also had just become serious with a local officer. So she knew how to word things and we went through a long(very hard for me) court process. She made me out to ge a monster.. I didn't understand what was even happening in the end.. So they win.. Get custody and also get the ruling to make all decisions for my child and that means whether or not I was able to see her.. So until she was about 9 and half I was getting visits and they were going ok. I mean I wanted to teach my own child how to do things like cook and prepare healthy meals. So her grandmother would always add new rules.. Like no cooking.. No helping with food prep.. No knives allowed.. She wasnt allowed in anyones car. So wasn't able to take her places.. It was tough but I still did whatever it took to see my child and spend the time the best way I could with her.. So two years ago I moved into a two bedroom unit.. I set up the one room for her bed and all.. Showing them I wanted more time with her and I wanted it to progress.. I had met a couple people and thought they were ok.. Comes out they are addicts and they have me over and pull out cocaine. I hadn't seen it in years.. I went right back to that addict thinking and used that night. I was honest with my ex in law.. said to her I messed up.. Well she used that and took my child away.. She is now having her believe some crazy things. I have tried to reach out with no success.. So now I am almost 3 months pregnant with a man who is great and he does a lot for me.. He loves me and he has never been involved with drugs so I feel safe.. Well my daughter has never met this man and now we are having a baby together... It is Canada day next weekend. I am already starting to show as I am thin usually and kind of tall.. So I want to share the news I want people who are in my life today to celebrate with me. I am also sooo scared to announce it.. I mean I have some of the family on that side on my Facebook. I know my daughter will be told and it willl not be the way I want her to find out and it will not be told her in a good way by any means!! I am scared to enjoy this time.. I mean I have come a crazy long way in almost 9 years and I know I messed up I now know that I have no power over drugs if they are in front of me.. I just want to be able to tell my own child.. I also want to be able to just enjoy this pregnancy and not worry that they will do what it takes to somehow make my life miserable again.. I am so torn as to what I am supposed to do.. I feel lost.. I feel happy... I feel like I was given another gift.. I have always wanted another baby.. I have always tried to do right by mine.. I mean I really wanted to be her mom too.. I hate feeling like this.. What do I do?? Do I share my news with the world?? Before the rumors fly? Help me!?! Please help?
