Stress Relief, Anxiety. What to do now.

I've been dealing with emotional pain and stress from a long time now. I've been diagnosed with Anxiety before. Now I feel like I am not able to cope up again. I am student as well as entrepreneur. I dropped out after passing out from school to do business. But after covid. My business stopped. I registered for many colleges but couldn't get into college due to high fees. I had forcefully to take admission in ignou when I didn't wanted to due to my parents being worried about my future. I've been trying to cope up with everything using self help audio books. They were helping but then again now my girlfriend has left me and got into relationship with someone else after a day of break up. I don't feel good. I can't focus on things which were important to me. I have been doing everything just to be with her. It was a long distance of 5 years. I don't feel happy, feel like eating, crying at nights, and overthinking. I feel so emotional at times. Please help me I don't know what to do now.
