Can you find some group therapy? You may find it beneficial to be with others who have similar troubles in a caring and understanding situation. It sounds like you have had some bad luck socially, which makes it easy/tempting to shut the world out, so learning to be open with others and to deal with difficult subjects with them may be beneficial to you in ways that one-on-one therapy cannot offer. It can also be helpful hearing others voicing their problems, as those may be things that affect you in ways you hadn't considered before too.
I'm with you on this. How on earth are one-off login events supposed to work? I want nothing about me logging on to be stored on that device or account other than, for example, the code I download. Maybe I'm missing something but the search I just did suggested connecting my phone via bluetooth, which is also not an option.
That's great! That is a scary thing to do, so way to go
