Depression and anxiety after cancer

Hello everyone. This is my first time here. I'm really hoping to get to know other people that are going or have gone thru what I had. My name is Sherlymary, Sherly for short I am 27yrs old and a mother to 3 beautiful boys. I am a stage 3 stomach cancer survivor. I went thru hell and back, as you guys all know how that is. But I'm happy to say its been 2 yrs since my last treatment. But there's one thing that I've noticed lately, and its really affecting me. When I was at the worst point in my illness, and felt the crappiest, it was spring going onto summer outside. Its been about a month now where I've had excessive anxiety and depression for no reason. But I noticed that when I stepped outside and the sun hits my skin, and I smell the fresh spring air, I get really nauseous and with lots of anxiety. It really takes me back to that spring when I was ill. I'm sorry if I confused you guys, lol, its hard to explain it. But I would really like to hear from anyone who has experienced this. I cannot have this much anxiety at all times, it seems like I'm just have a full month of "bad" or "off" days

Thank you for listening and thank you in advance for replying!!!
