Prayer Request

Please pray for healing for my 20 year old daughter who has clinical depression. She's on anti-depressants and is working with a psychotherapist. She started having depression symptoms when she was 17 and we've been praying for healing ever since. She has good days when I feel encouraged that she is finally healed, then she'll have breakdowns which leave me feeling discouraged. It is difficult for me to see her "suffer". I worry also that she might give up on God because of what she has to go through. My faith is strong but I sometimes get upset at God - it feels so unfair to have her struggle with this terrible illness. Why can't she be spared from all of this? I just pray that she will be completely healed and not have to go through the ups and downs. Thank you so much!
