I have no clue where to put this.

I just "met" with someone, over the phone, about getting life coaching. I feel drained now. It was a nice convo at first. We were talking about my self esteem and my goals. She didn't tell me how much she charged until after we talked, and it is way out of my budget. She offered to cut it in half, for half the visits, and it's still out of my budget, though I could do it if I sacrifice like, food, and living expenses. I said to her that I needed to think about it, and she said "usually people who think about it end up thinking too much and not doing it." I was firm though. I am going to think about it. But I am having a better day today, and I don't even feel like I need this today. Is it a red flag to try to get someone to agree right then, and not think about it? It seems like a red flag to me. I will probably end up resenting her if I do life coaching with her, because I will only have 425$ to live off of. She charges over 300 a month, and thats the low rate for me I thought I wanted a life coach to supplement therapy. But I cannot afford it. It doesn't fully feel right anyway. She's the life coach of my friend. But there is no way. Even if I do decide to do it, and make a budget, I'll only be seeing her 2x a month. For 325 a month. And...I just feel really turned off that she tried to get me to agree to it on the phone just now, and then said "I'm not trying to pressure you." I really want to achieve my goals and improve. She said it would be an investment in myself.
What do you think?
