Wow, that really sucks and I relate to this very much.

There are a lot of learnings that you can take from this though, if you're willing to try to look at this difficult experience from different perspectives. If it were me in this situation today I would try to think of all the possibilities like:

• I need to learn who is dependable for me and who isn't
• I also need to learn how to better compensate for my deficiencies when it comes to shared responsibilties
• Even though I need support with some things, I still need to get better at supporting myself rather than expecting to rely on others
• I shouldn't expect others to understand my situation if its not something they can relate to
• I should be more careful how I interact with people and with what I expect
