Sensitive topic / vent

Anyone else that has been suicidal before/done past SH starting to get those feelings here and there? I know it's very sensitive to talk about, but I couldn't bring myself to tell my partner that I wanted to km or sh. I'm 14 weeks into my pregnancy and it's been a long time since I had feelings like that. I haven't been with my partner long enough for him to have ever seen the part of me that has been defeated like that. He knows I have been down that road with failed attempts but seeing the struggle is different than hearing about it. I feel bad telling him cause it'll hurt him to know. Idk if it'll trigger anything since he lost a close friend that way. I don't want to do anything to myself that'll harm the baby but sometimes the thoughts get to be too much. I manage to keep strong the best I can but I dont want it to get to the point that I do anything out of impulse.
