Very confused and scared.

Hello, i have an issue man. I’m 14, my whole house is Liberal and accepting of anything. I’ve never really come to terms with it until recently when I started to fall for my best friend. I’m gay and closeted and I fear I won’t be accepted. I fear that I’ll grow up alone and I fear that I won’t have that perfect family when I grow up. I feel ashamed, I cry all the time. I feel anxiety 24/7 cause I feel like people will notice. I’m very alone. I want to be myself. This big weight is on my chest and I don’t know what to do. It’s all I think about. I want to forget everything. What should I do?
