I have the same problem as you flipping out on people especially my family and then I feel terrible after words, I hate it and I never know how I am going to act one minute to the next, I think one thing that helps though is staying away from toxic people, I just got rid of some people in my life that were not good for me, They were full of drama and gossip and two faced back stabers, If people are talking about other people behind there backs you can guarantee they are doing the same to you, I would rather be alone than have these people in my life, Try to get your stressors down and try to live more of a healthy life style, Try to get out and enjoy nature every day and excersise that might help, I know it is easier said then done, But I am going to try it myself
