Wheelchair usage

So this is kind of a discussion post and kind of a question post. I've been thinking about getting a mobility aid for a while, as I can't really go anywhere right now, and finally remembered to ask my physical therapist what she thinks. We talked for a bit about what makes me not able to do things and she said a wheelchair would be the best option for me (specifically one without a foot rest so I can use my legs a bit and/or push myself with the wheels) but I'm having a bit of a hard time coming to terms with it. For one, wheelchairs are expensive and I'd have to have my parents buy me one which I'd feel bad about especially if I rarely use it, on top of having to convince them to get me one. The second and harder one is I have this thing (working on it in therapy lol) where if something isn't super hard for me then I'm not trying hard enough and "taking the easy way out" and while I understand from experience that I can either not go to the grocery store or I have to have my mom push me in the cart (I'm 18 yrs old) to go, it still feels like I'm giving up in some way. I'm having a lot of internal conflict over it because a large part of me knows that I could be really good for me and I'd be able to run errands and go to stores and craft shows and all the things I love to do, as well as maybe get some independence back, but there's still that part of me that feels almost guilty about it, and worries that I'll become too dependent on it (even though I'm doing conditioning in pt). Has anyone else struggled with this? How/did you get over it?

Side note- I don't care about getting looks in public, I've dressed alternatively for years and have been in a cart in a packed target so at least that's not an issue lol
