Becoming depressed and loosing motivation for everything

Becoming depressed and loosing motivation for everything I have 25 years (F) and I am looking for a job for almost a year now. I had some interviews before covid (last interview I had in March) and now I am finally getting some responses from employers who would like to know me in person. The problem is, that my stutter is getting more and more severe (due to lack of communication, stress, depression). I had to cancel 2 of my job interviews recently because I couldnt accept the fact of getting rejection (again) . I cant prepare myself to go to an interview and stutter (I know I will stutter, because my interviews in past were pretty bad). I am scared I will become more depressed and I will lose hope. My field requires a lot of communication and working with people and I keep asking myself what the f*** I chose this. Probaly I though my stutter will go away :( I had speech therapy in high school and I remember I had to read aloud and be careful about breathing.This was not helpful because I dont stutter when I am reading, but when I have to spontaneosly talk with strangers.. Any tips for exercises? I tried reading aloud, mediation, talking on exhale.. Yes, I know those exercises but when I have job interview, nothing helps. I cant talk about this with anyone, my mother is in denial and my entire family does not even know I stutter. I cry every day, I dont wanna have that kind of life. Just venting... Thanks for any advice
