I know this is mostly my fault. I'm an introvert and I don't have many friends. My mental health isn't the best right now. I suck at communicating my feelings. 

Sometimes, I don't feel like talking at all and my gf hates it. I know it hurts and bothers her a lot. I love her so much. I wanna be better for her. I'm really lost, idk what to do. 

We have an amazing relationship besides the communication issues. My gf has only ever asked me to get better at talking and expressing my feelings. We've been together for almost a year now and i still haven't figured out what to do. I hate that I'm hurting her. I really wanna fix this but i don't know how to.

Why can't I just be a normal person like her? I hate being an introvert. I hate having extreme anxiety issues. I hate being anti social. I just wanna be a normal person and give my gf a relationship she deserves. She's amazing. I wanna make her as happy as she makes me. I love her a lot.

How can i get better at communication? Can y'all pleass give me some advice regarding this? 

TLDR ; My (18F) relationship with my partner (18F) has been going downhill because of communication issues. I need advice on how to fix the communication issue in my relationship.
