3rd trimester anxiety

Hi all, I’m nearing on 35 weeks and I just want to know that what I’m going through is somewhat normal and that I’m not alone!

Recently become very stressed all the time which makes me feel so angry almost always! I’ve got a terrible temper and I’m constantly worried about everything! The worrying and the stress along with the exhaustion is causing the most dreadful panic attacks 😔 is there anything I can do to help with this as I feel so sorry for my fiancé and 2 year old having to deal with my current mood ☹️ I feel at such a loss right now and just want to feel happy again 😔😔😔
