Anxiety disorder

Any help would be much appreciated 😁 I had a breakdown two years ago and diagnosed with anxiety disorder I can be ok for a few weeks then out of no where all my symptoms from my breakdown come back severe anxiety where I don't want to leave the house it makes me feel like I'm living in a bubble like I'm not here and I have the most scariest thing where I can not cope with life and daily struggles my body won't cope with stress I have two lovely children I don't want to feel like this the thought of my children starting high school makes me physically sick the thought of my loved ones dying is a out of control thought that is making me so I'll anything in life that is stressful my body won't cope with. I'm so scared to live but scared to die. I have just lost a friend who has took his own life last night I can't help but think I wish It could of been me but then my children are my world the love I have for them is so strong that I feel I can not watch them grow with life's troubles that are ahead of them 😓 please don't judge I'm at a loosing battle here where dying outweighs living. I no people will think be lucky I'm still alive when there are people dying that don't want to. But this is a illness out of my control. This is just not me or who I used to be I need help and I am not getting any. Do people live like this are my prescription tablets wrong? I want to be strong enough to get through this but if there is no light at the end of the tunnel I can't carry on like this 😢😢
