Medication/MIL

Kayla • 20 with the most perfect family. Blessed with one handsome husband and one perfect little chunky 9month old baby girl.
I got put on Zoloft before we even left the hospital... last day in the hospital my mother in law came up at 6am. First thing she does was start criticizing my breastfeeding, because I undressed my daughter to help wake her up and get her skin to skin to latch. Basically said I was doing it wrong and that I needed to dress her. She immediately took her from me I wasn't done feeding her.... Then she told me I wasn't allowed to have my cousin come to the hospital because it was her time with the baby and no one was ruining it. She literally had been at the hospital since 6am and it was then almost 9am. Told her to deal with it she was already here. I made my husband make her leave while I was in the shower because she was upsetting me and I felt like she had been there forever. When I got out of the shower the nurse and my doctor came in and asked me if I was okay. I didn't say anything just started crying. I literally couldn't help it. Everytime she gets around me I feel super overwhelmed. She invites herself to our house all the time and it drives me insane because she brings her three year old grandson who's constantly sick. He calls her mom, she fought his mom for custody. Her son(the father) lives with her and never has him. They let him do whatever he wants. He grabbed my daughter on the face after having his fingers in his mouth. She was three days old at the time! My first day home from the hospital. I had her and her entire family over we hadn't even been home 20mins. They invited theirselves over. Everyone came in started standing around me while I was breastfeeding and the baby was ripped from my arms while I was feeding her. I had just started a new medicine earlier that day and I was shaking uncontrollably. I tried to tell my husband but he was trying to fix ourheat at the time and wasn't listening to me. She pushed me out of the way while I was trying to change her diaper. I started crying again called my mom told her what was going on and locked myself in the bathroom. I came out of the bathroom still on the phone and she was shoving socks with shit on them in my face asking me where clean socks were. She could of asked my husband who was beside her or just looked. I started crying again now infront of everyone played it off like I was hurting and everyone finally left. She's just super controlling and always says does stuff that upsets me. When they asked me if I would want some medicine for ppd at the hospital my husband said yes for me. He makes me take it everyday. I don't wanna take it! I don't feel like it's helping me at all anyways. I literally told him I didn't feel like it was helping me and he said I had to give it time to work I've been taking it two weeks and still feel super overwhelmed when she comes around. I texted her and told her I didn't want her around with the 3year old because of flu/strep going around. That if she wanted to see the baby she had to leave him at home with his dad! I haven't seen her in a week now and I feel fine when she isn't around but as soon as she gets in the room I get upset and overwhelmed. Sometimes I get upset when the baby cries. My husband is watching me struggle with her, I start to cry because I don't know what's wrong with her and have literally tried everything he just watching me not helping pisses me off. I stay home with her 24/7!
