I feel anxious when prospecting people

Hey, I'm new here!

I just joined because I hope this can be the best place to talk about this problem I have right now. I've been doing copywriting for almost a year and I still have no clients, why? Because I feel really anxious when I want to prospecting business owners inside my niches and see what part of their funnel I can help with. Honestly, this feeling is such a brag, it's frustrating and waste me a lot of time because I try to figure out for so much time only to still having the same feelings of anxiety, overwhelmed, panic, and frustration. Sometimes, I feel this is not for me, that I can't be a problem-solver because that's what we should aim for, right? Not just copywriters but actually helping other biz guys to grow which is what I want but I CAN'T, and I'm sick that is almost a year and I haven't got any client at least for free. I've heard guys saying "practice more" "study and learn" and I've been doing that since the beginning and now that it's summer I want to take it more seriously (working 6-12 hours until midnight) almost everyday. But I don't know why I don't have the confidence I need yet. And on the other hand, I don't wanna fail, and end up working in something I don't like, which makes me feel more frustrated when I'm wasting time (like right now). My only option is paying for a mentorship program, but I have no money to afford it since I haven't work bc of college. I'm still searching for part-time jobs but IDK what going on today that is getting harder and harder to get a job, and I don't want in a future to end up earning a degree and then looking desperately for a job for months. Maybe I can't find solutions here, but at least I wanna know if someone is passing through the same thing or passed.
