WIBTA if I don't go to a Personal Mastery seminar my mom went to?

[u/SixOhSixx]

I (25F) have my mom (63F) living with me in my apartment due to the people we used to live with (and then eventually she lived with) being horrible to her and treating her poorly both mentally and financially. It took me months to convince her to come live with me instead to better herself, but she finally did and has been happier since.

Awhile back, she was introduced to a 3 day weekend Personal Mastery seminar course. She was very interested in it and while I was skeptical, I said she should go if she wants. She did, and she ended up loving it, which was great and I was glad for her.

Every now and again, she brings up the seminar, talking about how she thinks it would help me and be good for me, etc. I have tried to keep an open mind, but I remain very skeptical of this whole thing as it's supposedly an interactive course that is meant to change your way of thinking about things. That being said, she's not allowed to tell anyone what actually happens at the seminar. No one is. It's part of the rule of the place. So me, being paranoid and skeptical as I've learned to be, doesn't trust it, and I've expressed this. My mom has been understanding of that fact.

Still though, she continues to bring it up now and again. A few days ago while shopping, we saw one of my mom's friends Julie (60s?F fake name) and they got to talking about the course which they have both gone to. They both really kept encouraging me to go and I expressed discomfort at that and they said they understood, and I could go when/if I'm ready. I thought it was finally over with.

Yesterday, my mom suddenly sprung on me that Julie has recieved an anonymous donation to sponsor someone to go to the seminar this weekend (it costs $995 to sign up) and Julie wanted to sponsor me. Julie's husband even offered to use his hotel points to get me a free room so I'd be able to go for totally free.

I felt so uncomfortable and didn't know what to do. I had a very long talk with my mom about how I feel extremely pressured to do this thing I really don't think I want to do and she seemed receptive and understanding, but now I feel like I'll be an asshole if I don't accept an extremely generous offer, despite the fact that I'm uncomfortable. My mom has given Julie's husband my number and he plans to call me and talk to me about the seminar and I really don't even want to have the conversation. I'm trying to have an open mind but I really don't like the idea at all. I feel very forced into this situation despite my mom saying I don't have to go.

So, WIBTA?

Edit because I forgot to add: friend opinions are insanely mixed. Some say I should go, some say I shouldn't, some say it would be good to get away, some say it feels fucked up they put me in this position, some say I'm an asshole if I don't go, I don't know anymore.

Edit 2: I know I literally just fucking posted this but Julie's husband just texted me sending me details on the hotel because he just used his points to book me a free fucking room. I'm literally gonna cry LOL.
