Does anyone else feel okay for like a week and then feel absolutely terrible for like 2 weeks?

I can't even look at myself in the mirror. I've spent the morning crying, and I feel like I don't deserve to. I feel like I'm a horrible person or a... you know. I'm so sick of this. I'm just so tired of everything. I don't see my psychiatrist until two weeks from now. How am I going to make it till then? :( Even writing this post, I feel like I'm deceiving everyone and that I'm actually a monster. I'm so convinced of this right now. I don't know what to do. I was literally okay a few days ago. I don't even know what's real and what's not, like... I think I do? But everything is so distorted. I can't stop replaying memories trying to figure things out. I really need my psychiatrist right now. I feel like I need to confess, like I've been trying so hard not to, but every person I see, I just keep thinking about how badly I want to ask them if I'm a bad person or not, and that makes me feel worse. A good person wouldn't feel the need to ask that over and over again, would they? What if I'm just seeking validation because I can't accept that?

Lately I just feel like I’m on the verge of losing it and I don’t know why. I feel so uncomfortable in my own body. Physically and mentally. Not due to insecurity but just that something isn’t right… I never feel good, I’m always fatigued, my head hurts all the time, but my blood work comes back fine so doctor’s will do nothing. I have anxiety and panic attacks and recently I guess depression since I’m always down. I have relationship OCD so my partner deals with me not being sure of him constantly and it breaks my heart. I don’t want to leave him because he’s great but half the time my brain is telling me he isn’t the one. I keep counting as well, constantly counting every letter in every word and every word in every sentence… it just feels like I’m gonna go insane one of these days and I’m scared. When I talk to someone about this, they have no clue what to tell me or how to help. Am I alone in feeling this way??

I’m constantly finding myself getting irritated easily and sometimes it even confuses me because I was happy and fine two seconds ago. Like I feel emotionally unstable. I also randomly will get sentimental or sad and I just start crying. Is this just me??
