I feel stuck

I just need to vent. I have mood stability issues and depression in which I take medicine for. It seemed they were working very well for quite some time and now I've missed a few days due to a very busy schedule (which is no excuse, I just forgot) and now I find myself starting to get worse. Can that really happen just from missing a couple of days? I figured it'd still be built up in my system enough.... Anyway. In the past due to these issues I've had troubles keeping jobs. I get extreme anxiety and anger at the littlest things and have hard time controlling those (until I got on the right combination of meds) so I would miss work a lot and end up just quitting. I know that isn't good, trust me I beat myself up about it all the time. If you're reading this you probably just think I'm lazy and irresponsible but trust me it's a lot harder than you may think. I'm not looking for attention or sympathy at all. So because of these issues my doctor and I decided it may be good for me to work a part time job for now. Which I'm doing. But it's getting hard again (possibly from missing my meds a few days?) and I feel like I'm going no where in life. I AM NOT suicidial...just stuck. I feel like no matter what I do I always just give up on things no matter how hard I try and I'm not sure what to do anymore. I don't wanna lose another job but idk...please don't be rude or jusgemental if you choose to respond to this..I am my own worst enemy and I've got that covered lol.. Does anyone have any encouraging words for me? Maybe suggestions? :/
