First of all, it doesn't sound like you handle stress well. This could be a large part of the problem. Try and find some way to relieve your stress.
Secondly, being raw for only 3 months isn't that long. You body is probably still making major adjustments and throwing off toxins. Give it more time.
It's not uncommon for some people to lose alot of weight when they go raw and then when their body is cleansed they put weight back on.
"O Thou who has given us so much, mercifully grant us one thing more-a grateful heart."
