poor dear ..you have been dealt such a terrible deal in life so far..but those are the key words..so far....you are still very young with a lot of life ahead and a lot to live for with a son in your life that needs you..good advice above regarding MIND ..they can put you in touch with local help groups, folks who have experienced similar and DO know what you are feeling...talking does help..

also ask about a referral to your CPN..community psych nurse...they do home visits and crisis care team is available 24 hours a day for times when you fear self harm...
hopefully your change of meds will help but that does take time...
you have done well to get to this point....one step at a time....I send you my warmest best wishes and hugs...xxx
