Feeling like reaching out to an ex, even though there's never been any response

[homecoming]

That is true. Sometimes I do feel very empowered and 'better', but some days, like today and the past few days, I just feel low about things. 

Sometimes I don't care about the ex, and all that stuff, and know I'm better off away from it - the difference in feeling is amazing. I agree though, I think I'm just feeling down about other things - for example the gyms being shut. That would be my escape, typically. I've been working out at home, but it's not the same thing at all (for me!). But I agree with what your sister says, that's very insightful.
