I would be the last person to ask for friendship advice @outlander, I don't have any in real life and am only just starting to build them here 🙂 But I think the idea of friendship is that you are friendly to each other and feel friendly towards each other. From what your describing this person is not friendly toward you and you don't feel friendly toward them. You are under a lot of stress, when I'm under stress my brain seems to 'fire' quite differently, I see all sorts of conspiracies, am suspicious of everything and everybody and it feels like everyone is 'out to get me'. Maybe focus on the big hurdles first and then friends might be easier to understand. I also think it's important to like yourself, how can other people like you if you don't. If you like yourself enough, it might be easier to know which people you really like? I think I'm terrible at this advice stuff, but just want to say, I like you, enough to even feel a little Motherly towards you. I hope that's not offensive.
I'm heading off to bed soon. Good night, sleep well 🙂
