If it's been 6 months and your still feeling this way, I would suggest going to your gp. Tell them how your feeling, that your struggling to get back on track, and about the thoughts of suicide.
It's likely that a course of antidepressants, might be enough to get you back on your feet.
If you have found meditation to be helpful in the past it might be worth asking your GP about mindfulness.
I hope your able to push on through, take care.
