my friend (18 F) of one month might be moving too fast for me (18 F ) feel bad about even suspecting anything. is this manipulative behaviour or am i overthinking this?

we became friends on the first day of college like CRAZY fast. she's sweet to me, she told me about her past on the first day itself. we went out to watch the new spiderman together within 3 days of knowing each other, hung out the whole day.

she came to my house to do some weed, she got drunk with me, she made food for me like delicious vegan food especially for me and she made it REGULARLY. she's so so sweet , always walking the extra mile, she got me a kuromi keychain bc i like kuromi.

but idk i feel like it's moving too fast maybe... and sometimes it's a lot. she keeps asking me if im mad at her which im not. she kept blowing up my phone during my anniversary with my bf (and she knew it was my anniversary...) asking why im not responding.

and yesterday i told her that i dont really want to go shopping with her and she started talking about how her manic phase is ending and she'll be too depressed to go out later.

tbh i really dont feel like going it takes me a lot of energy to do little things like brush my hair or get out of bed, i dislike walking and im also on my period, broke, i have nothing to buy or do except accompany her and im recovering from a cold.

i suggested that we go, bc of her mental health thing but then she said that she doesn't want to anymore. she got me to beg her to go... and i didn't want to but she started talking about her mental health and you can't say NO to that...

and then i thought that she made food for me when SHE was sick, she lives so far but she's willing to go shopping close to my house, she shows up at my house even when it's flooded . she does so much for me, i should be returning the favour somehow.

TL;DR my friend of one month is moving too fast for me and i think she might have blackmailed me into hanging out with her? it's not crazy but is this a red flag or am i reading too much into thid
