< My life feels like it's falling apart ....
Not a burden at all. Sorry to read you're feeling other than 100%.
This is going to sound trite to the point of ridiculousness, but the only cure for any/all self-related maladies is genuine - i.e. practiced - selfLESSness.
So... find things to *do* that increase the chances of forgetting your self (note: the best such things tend to be helpful/nice things for others).
And if/when such less than blissful feelings return, get right back up on that self-forgetful, others-giving bike, and ride the living fuck out of it....
