I was diagnosed just a few months ago but I had suspected for a long time. I didn't have true mania until about 5 months ago before it was hypomania. I also can get odd sensations in my head. For me it's more like there is electricity inside my head buzzing around. I feel like I have an arc reactor in my brain. When I'm depressed I feel like there is an empty black space in my chest and I feel very heavy.

The medication decision is a hard and personal one. Have you spoken with a therapist or psychiatrist yet? I'm on lamictal and still skeptical of meds. It seems to be working and I'm getting more even but I'm still deciding if it is right for me. One thing a friend told me that helped a lot on my decision to start meds was this, "You are still fully in control of your medication. If you don't like what the doctor prescribes, don't take it and get something you do like. You can quit any medication as long as you do it safely". Remembering that I was in control made it less terrifying for me
