Hi roomoo, try and stick with it, it takes a few weeks if not more to settle in your system, you will start to feel better very soon.
Have you ever had therapy before? I've had it for a few years and I couldnt recommend it more, it truly is wonderful, you just need to find the "right " therapist, just sit and talk, what ever comes into your head say it, how you feel, what upsets you, how your days been, whats made you happy, what has made you sad, what makes you feel so passionate you could burst, and gently talk about whats scared you and deeply hurt you.... sorry for going on, I just want you to get an idea.
I understand that you feel anxious, thats normal, just go wit it they are there to listen, thats why they chose that line of work, generally they have been through something themselves so dont feel alone or fragile when talking to them. They will help you make sense of your life, your thoughts, behaviour, actions passions and help you become stronger, they will empower you! I promise.
try and stay strong for yourself, so can feel good about who you are, do something lovely for your children and yourself each day which will make you like yourself and not feel the need to self harm, I dont know you but you are an amazing women, you have two beautiful children, you are their world and they love you unconditionally.
hope this helps you as I do go on abit xxx
