Recovered from anorexia yet no period and breast growth

I'm a fourteen year old female with no breasts and no period. I feel so alienated and there is nothing I want more than to just have a normal body and not look like a skinny boy.  Since a young age, I have always been bigger than my peers, partially because of genes and partially because of my muscular swimmer body. I was bullied for my fatness and I would cry myself to sleep thinking about my fat thighs. So when quarantine started, I was eleven turning twelve, and I started working out and eating less and less to lose weight. By November that same year, I had turned twelve and had a bmi of eleven. I was admitted to the hospital and stayed there for almost half a year and gained enough weight to reach the bmi requirement of 17.5. I was happy and felt free, but I then started losing weight again as I felt increasingly uncomfortable with my healthier body. By july 2021, I was in hospital again with a bmi of 13, and I physically felt worse than I did at my lowest weight. For the next couple of months I became a revolving door patient, but in december I had enough and started recovering for my own sake. The first months were really hard but my work paid off and I felt happier and excited for the future. In june of this year I turned fourteen, and I finally reached a healthy weight. I had had discharge from my vagina for a couple of months, I felt small lumps under my nipples and I was growing hair in my armpits and around my vagina. I was excited to finally get my period and get breasts like my friends, but now four months later, nothing. I feel so hopeless and I just want to have breasts and a period. My chest looks like a boys and I hate it so much. I'm scared that I have done so much damage to my body that I will never have breasts or a period, and I am considering breast implants when I am legal because I can't deal with my current body. I feel happy in all other senses, I take antidepressants, I'm  doing well in school, I have friends and I swim once a week. My counselour at my ED clinic says that I will start puberty soon enough and that she's happy with my weight gain, but I can't help but feel sad over my underdeveloped body. I have grown in height, over four centimetres in a year, I have pimples, BUT STILL NO PERIOD AND BREASTS. I am so desperate and I need answers as to why they are not growing. In case this will help, my mother got her period at age twelve and has a large chest, my current height and weight is 166 cm and 50kg. Someone please see this and help a girl out. 

Thank you.
