Needing to vent

I just needed a place to vent , i don’t have many friends and i don’t like discussing my mental health with my bf because i feel like he doesn’t understand. I suffer from severe anxiety and depression. Lately i have been feeling so overwhelmed and upset and i don’t understand why. I know work is stressing me out but other than that idk. I just feel like everything is overwhelming and out of my control and i want to cry all the time. I am currently on no medication for my anxiety or depression i am scared to go to a doctor for it because i don’t like talking about my mental health i just get really uncomfortable and start crying. Any advice on how to get over my fear of going to a doctor?
