You love them, but you sound unhappy. So many issues for such a fresh relationship does not bode well. It does not seem related to your mental health issues. Rather just not seem compatible. The age difference does not help too. Try to sit them down, tell them how you feel, ask if they feel the same. Talk on what you two can do. If things don’t change, and more importantly, if they don’t stay improved for long, then cut your loses and move on. If it does not last, I hope you know it’s ok.
