It makes me happy you said that, that you think these things are just a part of which makes you who you are. Because I feel the same. For awhile, I thought it was just such a normal thing for me to act weird sometimes, it's only when some relationships became strained/ended (and when the restlessness and depression got too hard to handle) that I realized I probably needed help, though I didn't know to what extent. But it's important to already have such an acceptance of yourself now. Some people have hated themselves because they feel like they're broken, and it only makes things worse for them. What helped me with the fear about therapy/mental health and everything in between is doing a lot of research. Perhaps looking into the best therapy options gor a person in your situation could help ease the nervousness? 'Cause I think you'll greatly benefit from therapy. I've found some tools tailored only for me from seeing a therapist for only a few months. For now while you're still deciding, research and writing reminders, thoughts, buying a bunch
of post-its and having a giant white-board calendar is what helps me. I looked into what my triggers are (caffeine can get me hypomanic, for example) and having a regimen (like exercise) to add in more stability helps a lot too. Once again, good luck!
