Medication

So I have complex PTSD and MDD. The PTSD makes me crazy anxious but the MDD makes me super tired and lethargic. This makes medicating pretty difficult, because anti-anxiety meds are predominantly "downers" which would worsen my lethargy (one med I was on had me uncontrollably tired to the point where staying up past 6 PM was not an option) but the antidepressants increase my anxiety (which exacerbates PTSD symptoms).

I was curious to know if anyone has run into this issue before and if they were able to find anything that worked?

I've been off meds for two years now and some things are just becoming too unmanageable.
