Jealousy? Envy? What could it be?

hello! so, a few weeks back I made a post in here asking if therapy was scary. Since then, I’ve started seeing a psychiatrist and was diagnosed with Major Depression, Major anxiety, Bipolar Disorder and mild PTSD. I have had the worst time sleeping for a month now, I’ve been having migraines everyday, my mind races constantly and it all feels never ending sometimes. I was prescribed an antidepressant which helps with insomnia, migraines, anxiety and depression & was instructed to take it everynight 2 hours before bed which I’ve been doing & so far, it works well. I haven’t had a migraine since starting & i sleep better than I have in awhile now. I was really nervous going into my appointment but I ended up feeling calm after talking with the psychiatrist for a bit. He was fantastic! A great listener & had a very calm demeanor, which made me feel much better. I go back in December for a checkup to see how my meds are working. So that’s an update on that & I am so grateful for everyone’s kind words on my post!!!

but there’s something I have a question about. I have been getting really irritated by the smallest things. Whether that be people or an event that occurred to trigger my irritation. I wish I didn’t get so angry & irritated so fast. It makes me feel like I’m taking steps backwards. Why is this happening? Why do I get so irritated so easily over the smallest things? What’s the reason?? Is it just my brain? Is it normal? How can I help it? How can I stop getting irritated so fast?

another thing..idk if it jealousy, envy or just plain aggravation but yesterday my boyfriends sister was told that she was going to going with her grandma to town to buy her an iPad. For some reason, that made me angry. I don’t know why though because I don’t want an iPad, I have no use for one. & in my mind I just kept telling myself that she’s so spoiled. She’s 19, no job, doesn’t go to school, she goes out everynight until about 1am with friends & her mom pays for it even when she isn’t in the best financial position. My boyfriend had to get a year 2001 vehicle and she got a 2020. My bf was told no one could afford to get him a new phone. He has an iPhone X, she has an iPhone 15. My bf was told he couldn’t go to college bc it was too expensive, she got her college paid for in FULL by the same mom that told my bf he couldn’t go & she ended up dropping out after 2 months. Am I wrong for feeling angry about her getting an iPad after she’s already had everything handed to her? My bf was forced to get a job by his mom or else he’d have to find somewhere else to stay but his sister gets to sit on her *** at home all day until she’s ready to go out. She never cleans, never cooks, never does ANYTHING around the house even when she’s here all day & my bf gets in trouble for it when he’s been working for 12 hours all day. Whenever his sister was told that she would have to wait until later this week to go get the iPad bc their grandma (who was going to pay for the iPad & also has dementia) wasn’t able to go out tonight she pitched a fit bc “she canceled her plans to be able to get the iPad” & was saying “now I’m never gonna get it bc she has dementia so she’ll just forget” & that really irritated me. Am I wrong for being irritated? Is it just jealousy bc she gets any and everything she wants? Is it reasonable? Am I just thinking about it too hard? I don’t know. I don’t know what’s wrong with me. Eveytime someone brings up her going to get an iPad I get so irrationally angry & have to walk away bc it makes my blood boil. Why though? Does anyone know why? Am I being dumb? Am I in the wrong by feeling this way? Or is it valid for me to feel this way?

I need opinions, advice, anything. I want to feel normal. I don’t want to be so quick to anger.

thank you in advance, for the help, support & advice ❤️
