Dear Girl,
What you are going through is extremely common therefore very normal. With whatever information of you have given me, it seems you have Depression.
Next Steps
Seek help from a clinical psychologist and a Psychiatrist . They will help assess your problem. After that seek help of a psychotherapist/ psychologist. Help is available online or you can visit someone closer to you. You can connect with me incase you don't find anyone near you and I will assist you in finding a goof and trained therapist. Online Video therapy is as effective as Physical face to face therapy.
Health Tips
Please do not delay seeking help. There is nothing to worry here. This is normal and common. You are not alone or the only one
