Might be a long one as will try not to drip feed...
Background; DH and I have been together since teens, now in late 20s and married for 5 years. SIL is my age and lived with us for a while before meeting her DP. We were all very close and have been on4 holidays together, often go out for meals and drinks and I would have counted her as one of my.best friends. Both guys are very very soft and kind and were both more assertive women and quite similar so both relatio ships have similar dynamics except she is quite feisty and argumentative whereas I avoid confrontation that isn't necessary.
DH and I got a flat in a nice part of town and SIL and DP moved to the same street. First few months were great, always in and out of each others homes etc. About a year later, 2 things happened a month or so apart. I had a mental breakdown which caused me to be off work for 6 months and DMIL got diagnosed with cancer.
Around this time I tried very hard to be there for SIL but she's very stoic and doesn't really 'do' feelings, and she shut herself off a bit. I respected that and just checked in every now and again, invited her to do things and left her alone when it seemed she didn't want to be bothered. She never asked how things were with me - TOTALLY understand and didn't expect anything from her at all, this is just for background.
I was really quite isolated during my time.off work and felt embarrassed being off when my MIL was going through chemo and radiotherapy and then a mastectomy; I felt very 'babyish' and unworthy so avoided bringing anything about myself up when we would all meet as a family. MIL and I have a lovely relationship and she would ask genuinely how I was which was so wonderful but embarrassing as I couldn't help but compare what she was going through (fighting for her life) to what I was going through (endangering and trying/wanting to end my life).
I have SIL, MIL and MILs DP on Instagram and used to use my IG as a bit of an outlet; I've always used.it to write blog style posts about things I do or think and keep.it fairly private, but during my deepest darkest moments it felt like a bit of a life jacket to be able to get my. Thoughts out.
SIL is infamous for hating social media and only has IG to keep.up to date with events. Hers is totally blank. So, a few months in to this whole thing I notice every time I see her she's going off on one about how she hates 'dickheads who share their lives on the internet' at great length, many many many times. She also frequently disparaged 'dickheads who.go off work with 'stress'' as she works as NHS professional and thinks paying people MH sick pay is wrong.
One night after this I got very embarrassed, changed my IG name and blocked all DHs family and changed my user pic so they couldn't see me. I felt so.embarrassrd and small and I just thought I didn't want her to think less of me, and she had already cooled.off a lot towards me during this period.
Over the past 10 months she has grown more and more. distant from.me. MIL is doing amazingly and is back at work and I am.back too. However, our relationship has never been the same.
I spoke to my dh about it and said I felt like I'd lost a best friend and he comforted me but just said that this is how she can be. We were friends for.over a decade and she seems to.have dropped me because of.my MH even though it has never ever impacted on her and I don't know if I'm unreasonable to be really hurt by it or if it's just something I should.let go of?
