Trying to do things right but still depressed

I have bipolar depression and I am trying to do things right in the last two weeks I mean started exercise a healthy diet started further with my italian lessons and Reading. But I am still depressed. Despite meds despite working out despite walking and everything else. Maybe its too soon to see results I just started these in the last two weeks. Have been depressed for over 3 years I do take meds for depression. I tried lots of them but all made me worse until these I am on right now. Maybe I should accept that there are other Deep Root caused that need to be addressed in therapy? Oh forgot to mention I had a gluten intolerance and ignored it just until recently when I started a gluten free diet. I know gluten can play a role in depression in gluten sensitive people. Its not normal to start and feel sad out of nowhere even when I am working out I sometimes feel sad. Its difficult I needed to vent . Thanks for Reading my post and I wish you all a good recovery from this disease stay strong!
