What did you do??

If you struggle with depression, anxiety or any type of mental illness what did you do? I've been struggling for a long time with thoughts of suicide, sever social anxiety and panicked episodes. In other words, when I'm down, I'm down. A ton of mental illnesses run in my family all of my siblings struggle and my two older sisters are medicated but my brother and I are not and have never done anything for it though he has it very bad and he has attempted suicide multiple times, a drug user and probably has bad bipolar disorder and maybe ptsd. Sometimes it's so bad I don't want to continue... But I think of God and my husband and just break down bc idk what to do or why I have these thoughts.. how did y'all go about getting help??
