Communication problem

It's an "alright" day today. Mom called again in the morning. We were talking about the same old thing. I felt so annoyed, didn't know how to deal with her anymore. When I kept myself silent, she was pissed. When I started talking about my own opinions, she thought I offended her or something, which I totally thought I didn't. Honestly, I was just trying to express myself and hopefully she wouldn't be too stressful about everything. Well, I seriously think that I am having serious communication problem with her.

Talking about communication problem, I found out my communication skills got better after I started volunteering. Then this skill got me a very nice job at Laserlife, where I strengthen this skill. I can talk to people with different background, different age groups or different believes. I was so confident that I could deal with different kinds of people. However, right now, I haven't worked in that clinic for a while, talking to people is no longer one of my strengths. I am nervous of strangers again. I am so, almost too quiet when I am within a group of people that I don't know. I just don't feel like talking at all. Man...I am losing it.

Strangers. I started to address the problem lately. This problem cannot be solved unless I take the initiative. Again, I am the only person who can help myself. How sad.
