Am I crazy?

Laneeka • 21. Northern VA. Love your life because you only live it once.
So here's the deal. I think I have anxiety but I don't have full fledged panic attacks mine are different like something will trigger my "anxiety " I get very quiet and I'm like stuck in my head I'm just thinking and thinking of ways to fix whatever so I can calm down then if you talk to me when I'm in my head I get all angry and mean. I probably look crazy because I'm just staring blankly but I'm thinking. That's one thing. Another thing I feel like literally everybody is talking about me when I'm in public and it really stresses me out. I get so nervous but on the outside I seem pretty calm and content but on the inside I'm freakin losing it! I don't know what's wrong with me but I hate feeling like this I want to have clear thoughts also is it normal to stress over things that you've said wrong or embarrassed yourself about that happened years ago? I know you guys aren't doctors but I just want to know if I'm normal or should I consider talking to somebody? I get what I think are possibly anxiety attacks often.
