Been on my own for 2 years with young dd, spent the first 18 months getting through exdh's cruel behaviour towards me/making sure dd was emotionally okay/making sure i was financially okay/generally just going through the motions tbh.
Since the very end of last year/start of this one the dust had settled, and I started to think about me. I realised I had no friends (i have one, but i feel like i don't connect with her really now), no real interests.. Ive let myself go physically a bit but cant bring myself to care much. I dont value myself, i dont trust people and i dont know how to "start again". All i know is im getting older, i look at younger people in their twenties and envy them so much 
Has anyone else ever been through this? How did you come out the other side?
I want friends, fun, to be amongst different people and eventually a good partner who loves me. I don't know how to get out of my head/crippling self esteem and trust issues!
