Tinsel, you sound like some of the ignorant staff I have met working as so called HCP. Of course mood stablisers can be uped, including lithium.
OP- bipolar is shit, the guilt just for being ill is bad enough let alone after doing a bad thing. I was really high recently and put myself and my children in danger, We have had to cancel a family holiday, my DH is really far behind work, my DM made herself ill trying to look after the DC. Guilt guilt guilt.
The best thing you can do to alleviate yhe guilt is to change your lifestyle to make it as healthy mentally as possible, the best things I have done ( and god I wish I had done them at 26) were
Mindfulness/medication
A low GI diet
Moderate exercise
Medication management
That sends a very strong mrssage tomthose around you that younare doing everything you can to stop yourself getting ill again.
Killing yourself would destroy their lives for years. I have lost friends through many means but the two through suicide were horrific, what it did to those close to them was vicious. Jt left a huge unbelivably gulf of endless pain, guilt, anger, sadness far worse we suffer or yhan you vould cause by living.
I can see how bad you feel about hurting those close to you, so do things to make that better not a whole lot worse.
Take it slowly, the new meds are likely to make you feel really shotty for a while, Inalways react terribly. Take it hour by hour and you will get better over time
