Constant Splitting: Need Advice

Well I'd personally try to first find the cause of it and work on combatting the source. For us the source of one of our splits was due to the fact one of our alters couldn't accept himself and had to split from the parts of himself he couldn't accept, this creating another alter. It may be that you're going through a phase of self-denial and need to practice self-care or self-love. It could also be that you're going through a stressful time in life and feel like you need the extra support. My best advice though is to find the source first and go from there. One step at a time.
