Mental Health and strength to get better

Hi my name is Kelsey and i'm 23 years old. When i was 18 i was diagnosed with Polycystic Ovarian Syndrome which has, well taken over my life. For the past 2 years i have suffered majorly with mental health and anxiety and have had a number of attempts to end my life. I have gone through counselling and CBT therapy but have always done this along side work which there has always been a pressure in the back of my mind to convince myself im better so i can get back to a 'normal routine'. My depression has stemmed from my weight due to the PCOS and in 5 years i have put on 8 stone which PCOS makes it easy to do this and near impossible to lose it. I am currently on a waiting list to have weight loss surgery but because of my recent suicide attempt i have to wait at least a year to really get myself better, which i want more than anything. Due to my mental state even getting out of bed was so hard and has resulted me in leaving my job to 100% focus on my health and really get through it this time. I live with my partner a year younger than myself who is an apprentice for an engineering company. He is very understanding of my health and why i have left my job. Although he says he is fine i know this whole thing is taking a massive impact on him and his wage alone we are really going to struggle. Last year he proposed to me! and i then went on to winning a wedding venue local to me and we have set a date for 13th November 2021 and i want to be here more than anything to get married to my soul mate. Any help would be appreciated to make this day as magical as possible for us. Thank you
