When is enough enough?

so when is enough. How long do we suffer before we say enough is enough!!! Not going to get better only worse. What if I can't take it anymore. My hole life people keep telling me it will get better but it hasn't. I can't do this anymore! I'm tired. Things have gotten out of control. I can't support myself anymore. I've been to doctors all of them no one can help me. Can't afford to keep seeing them. I'm up all night. Have been crying for 4 hours now can't stop. Have no fight left in me. I'm going to end up a burden to my kids. I've been fighting my hole life for so many years I have no fight left😢 When is it enough enough!! no one can help me. The bipolar has beaten me down for so many years I can't get up anymore!! How long should I suffer?????
