Look up on you tube something called a 'mind map' it can teach you to either organise your thoughts or plan things by breaking them into small manageable pieces. For example you could do one focused on building friendships and think of all the ways and opportunities where you could do that. It's easy I've done a few in the past
Thanks so much for words and advice!
Sorry thar you are going through so much. Start one step at the time. Start with something small as achievements motivate us to get going. You got this!!
