Hello all, I posted here once a long time ago asking a few questions and recieved lots of very knowledgeable responces back. Recently I’ve been under a lot of stress and I’ve made the decision to return to yoga to help calm it, and wondered if I might ask you all for your help again 
Without going into too much mind-numbing detail a woman whose company I am forced into on a regular basis has been harassing me via various methods, mainly by talking about me behind my back to people we are both friendly with, spreading unkind rumours, freezing me out of conversations and simultaneously being over friendly and extremely over familiar, grabbing my arms or hugging me or asking odd personal questions. This escalated over several months until recently I reached my limit and sat her down for a talk. The talk ended with her crying hysterically and denying everything, and now she doesn’t even pretend to be a friend which is a mild relief.
Worryingly, it’s been several weeks since the final talk but if I’m around her or even just think about her I get a terrible acheing knot in my upper abdomen. Sometimes it’s so painful I double up or have trouble standing straight. I feel awful, and I’m scared I’ve lost control of myself or I’ve developed some sort of mental complex 
I’ve also started having problems sleeping and wake up in the middle of the night thinking the whole situation over. I’ve never suffered from any kind of anxiety or depression before, so at first I had no clue what was going on and thought I had a stomach bug!
A family member suggested I see a hypnotist, but instead it reminded me of my yoga that I abandoned a year ago after emigrating from the UK. So I’ve decided to turn to yoga again before even thinking of going for counselling or hypnotherapy. I’m still searching for ANY yoga class in this rural area I can attend, so in the meantime I want to practice on my own.
My skill level is fairly novice after such a long break :-? I’m looking for simple postures that’ll help me clear my head and physically prevent these cramps from happening. I’m also looking for some other postures that’ll really tire me out before bed so I’m ready for sleep and stop waking up. I’ve been doing some light meditation and breathing exercises, but my concentration wanders within minutes. I’ve been doing a lot of child pose these last couple of days and it seems to be having an effect, but I’m stuck for other ideas and lastly I’ve never been a remotely spiritual person before, but this whole episode of my life has really changed my perspective, so a little development in that direction won’t hurt either. It’d feel nice to have some support. I have a very loving and caring boyfriend who I’ve been with for years (he’s the reason I left the UK 
) but he doesn’t understand that a cuddle and telling me ‘not to think about it’ just isn’t working (which makes me feel even worse because surely in a normal person it would work?). He’s already worried because he knows I’m not sleeping and the last thing on earth I want is for this to affect my relationship with him!
Help!
