Definitely better to stick at the counselling, it's not the counselling that's making you feel shit! (As long as you have a good counsellor that you're comfortable with.)
I still remember how crazy I felt, totally at sea, like being in a storm. It was so hard to try and get on with everyday life, I felt like I was cracking up every day on the inside, whilst trying to keep a mask of 'normal' on. Counselling helped me to hold it all together, I wouldn't have survived it all without that.
Just after I replied to your post, I opened my book and the first paragraph I read just seemed so relevant to what you're going through, I thought I'd copy it in for you. It's from 'Buddhism for Mothers' by Sarah Napthali. Buddhism may not be your cup of tea, but I found it useful to staying calm when I felt anything but. Anyway, here it is...
(it's talking about how negative feelings are bound to cross our mind at some point and the aim is not to get too attached to them, treat them like visitors, they come and they go)
"When we ignore these visitors or distract ourselves from the presence of disturbing states of mind, we lose touch with our feelings and our wisdom. We might seek to numb ourselves by indulging in alcohol, drugs, shopping, binge eating or blaming. Running away from our problems in this fashion empowers the negative mind states to do more damage than necessary and we miss the opportunity to heal ourselves with awareness.
We may be scared of our mind states. Perhaps we harbour painful memories of times when we let them run out of control or times when we mistook them for who we were. Yet we don't have to act on what we find in our minds, infact, our actions are likely to be wiser if they come from an awareness rather than a denial of our more obnoxious visitors.
Accepting the existence of feelings such as hatred, loneliness, confusion, anger, guilt and resentment, is the only way to transform them into more wholesome states. This is the path to wisdom - accepting life's unpleasantness, without fighting, fleeing or forcing it out of our awareness. We also remind ourselves that by fully experiencing our emotions, we deepen our understanding of others' pain and joy too."
I hope that (rather long!) extract is helpful to you, it just seemed like a happy coincidence that I was reading it right at that time.
Good luck with it all, hope that light at the end of the tunnel reaches you soon
